View Full Version : 2 18's in a RANGER!!!

Well, this is the build I've been working on, and finally got finished about 3 weeks ago. Everything is finished, except the amps are on their way right now (Hifonics Bxi2608's). Since I'm still in high school, I have unlimited access to pretty much any machine I want. And, since our school recently got a CNC machine, it made cutting the circles out of the baffle a breeze (It took a total of 15 minutes to cut ALL 3 baffles). And all the cuts it made were perfect, which helped out alot. Pretty much all of this started when a kid I work with got a listen to my setup, a Bl12. After that he was immediately impressed and wanted a Fi setup. His old setup was 4 CRV 12's powered by an old Kicker 1000 amp. I believe the highest he hit was a 141.2 on the TL. So, after talking to him about what he could do, we finally decided on this setup:

Subs: 2 Fi Bl 18 D1

Sub amps: 2 Hifonics Bxi2608D (will be coming Thursday)

Speakers: 2 Alpine Type S 5x7 component sets, and 2 Alpine Type S 6x9's

Speaker amp: Kenwood KAC-6402

Headunit: Alpine 9881

Wire: 30 ft. of Knuconcepts 1/0

Deadening: 63 sq. ft.

And just some other random stuff: all 14 gauge speaker wire, 4 Everstart Max batteries, and push-button start.


The first thing I'll start with is the building of the box. The box itself is about 14.9 cubes, with 2 6" aero ports tuned to 32 hz. I used about 2 1/2 sheets of MDF, which I was surprised that was all I used. The demensions on the box are 46" wide, 37" tall, and 18" deep. I really wanted to have the flush mount look, so the front baffle is 2 sheets thick, with a third sheet as the flush trim piece.

After I got the box made, I wanted to test fit it into the truck to make sure it fit, but of course it wasn't so easy. The only thing I had to do was make a small notch in the bottom of the box so it would slide over the transmission well inside the truck.

But anyway, only after I got the box finished did the equipment come in. The headunit was already put in, and so where the speakers, but everything else came in after this point.

And since this kid's dad is a carpet installer, I covered it in a medium gray felt. If I didn't get it on right the first time, it would have been fine because I cut this off a role that was 12'x50'.

So, after getting the box carpeted and all that good stuff, we finally got to put it in. If you notice, I've got a dead-blow hammer and a 2" end wrench to pry it into position. It went in perfectly, but the box weighs so much it wasn't easy to move around.

And so now we wait on the amps to come in. Once we get them in, I'll be sure to make a video. We did hook it up to my amp (powerbass asa1500.1) at 1 ohm, and it was LOUD. I do have some video, so i'll upload them here in a minute. I almost forgot, here are some random pictures of the tearout and laying of raamat. we did 1 layer on the floor, and 3 layers on the roof. As you'll see in the video, 3 layers didn't help a whole lot, but it's better than nothing.

Box looks very nice, but I would have added bracing for the top and side walls. They look too long to be unbraced, especially with 2 18's...

Guess you'll find out when the amps come in.

Well, he's actually got something like 15 percent tint, but he's going to get an alarm pretty soon. But I just found this other video, so enjoy. And just remember, I'm only feeding this thing about 700 per sub watts, which will be about half the power he will feed it once he gets his amps in.

Thanks guys. I'm really hoping to hit close to a 155 when we go to comp this summer. I think we might have to go over to a good audio shop once he gets his amps in to meter it before the season starts. The only thing that ***** is the closest nice audio shop is 60 miles away. :(

why not make it a complete wall. take another piece and take it right up to the roof.

bigbud747
05-03-2008, 11:57 PM
We kind of decided to make it like this because he's not keeping this truck forever, and it would be easy to take this box out that try to take a wall out. And since I only had his truck for 3 days, it would have been hard to make a complete wall in that amount of time.

well, not really, it would just be a trim piece, mainly for aesthetics.

looks nice, but i do question the amount of port area, even though aeros help reduce port noise, id expect the port velocity to be rather high

bigbud747
05-04-2008, 12:35 AM
Even playing the lows, when the subs are really moving air, there really isn't that much air coming out of the ports. I've got a 3" aero port in my box(the biggest I can fit), and it pushes the air out, a lot more than this setup.

Once we get the amps in, we'll pull the subs out and put screws throught the back of the box into the back wall of the truck, and throught the bottom in two seperate places. When he slams on his breaks, the box does tip forward, so we'll do that asap.

And thanks Rawr, that felt was a lot easier to put on the box, and looks alot better than the box carpet you get off crutchfield. And it's very durable to boot. I'm just very anxious to get the amps in to start pounding. Once they do come in i'll be sure to get video, and pictures of the amps.

I'll have to talk with this kid, buy I'm sure he wouldn't mind giving you a demo :). He's planning on going to most of the creative audio comps in joplin, pittsburgh, and springfield. Are you planning on going to any of them?


There we go, got the location fixed :)

Nice work. I would have def made another baffle for a front plate to cover up to the roof. I like the battery rack in the jumpseat hole. I run wet batteries in side my truck I just keep them covered in case they sulfate from an over charge. Very Nice overall.

hadn't planned on it, but i have been looking to get my setup metered, i think it'll break 50's, even in its daily tuned box. i'm in wichita, and work at spirit (boeing) so i dont get many days off. do you have any dates for those comps?

Yeah. If you go to midwestspl.com right in the middle of their home page is a smaller scrolling page with all the comps held by creative SB audio, and mach1. But I'll just copy and paste the list that's on their website so you don't have to go to the trouble of looking.;)

Well, here ya go guys. The amps came in yesterday about noon, but I had to wait till we got off work to install them. We also picked up to distrobution blocks for the power and ground, which we mounted on the box. All in all, it took just 1 1/2 hours to put the amps in and get it tuned and running. All I can say is, IT IS LOUD!!! I can't wait till these subs get broken in all the way (they pretty much are broken in from me playing with them). And we are both going to competion next sunday the 18th to get this thing metered, and my bl metered. And videos won't come till tuesday, because I'm driving it to school then and showing it off. Just hope the cops don't give me a ticket. :(:D

why did you put the gain knobs in the middle of the box and the power\ground blocks on the front?

it looks terrible. put the blocks on the side and remove the gain knobs.

otherwise it looks like a fun project and im about to do something similar with my gti and some konaki motors.

bigbud747
05-11-2008, 01:31 PM
Well for one, we think it looks pretty cool with the distrobution blocks on the front just to show people how big of wire we're running, and the fact the it would be impossible to mount them to the side even with a 90 degree drill head. And, when the seats are in, you can't see anything but the top of the bass knobs, which are only used as a kind of volume control when he wants to play his door speakers loud, but not his subs.

running 4 guage to an amp under a foot or two away for a daily driver is perfectly fine.

lets say the amplifier is only 60% efficient, battery is at 13.8, 4 guage an 5 feet long - and i know the amp is more efficent, i know the voltage should be higher, and i know the wire will be shorter, but im giving it paramters over what this kid will be using.

BCAE1's amperage calculator listed on this page (click here) (http://www.bcae1.com/wire.htm) gives a maximum rating for this wire, and that is 393A with a .5v drop. and the amplifier would be able to sustain 3251watts.


so im quite sure that less than 5 feet of 4 guage will be able to sustain almost two 2000w amps, let alone one.


i agree with bass knob comment.

have a nice day :)



//edit to mikeyb

I'm not sure why everybody is down on the speaker wire. I used 12 gauge. Is that so bad? In the video that was something like 18 gauge, but that was just hooking my truck to this one, not what we actually used for his setup. And at the most I used 3 feet to go to the farthest amp, so I think its just fine the way it is. It all turned out good, everybody i've shown it to was blown away, and it's loud, so what more could I ask for.

speaker wire is fine, there will be no audible difference between 16 guage and 8 guage, so 12 awg is fine

The wire in the pictures of the sub sitting on top of the box is 18 gauge. But that was just for messing around with the subs when they were on the shop floor. We upgraded to 12 gauge when we put the subs in. Also, I'm going to bridge the amps up tomorrow where I only have to set on, and the other one will take them settings, so it will be easier to get a more accurate tune for both subs.

1. Bass boost knobs are stupid, you're going to clip the signal
2. Brutus amps **** the big one, for 450 bucks you could have gotten GP3000Ds, which will put out oodles more power
3. The box looks nice
4. I think you should have gone with a little more port area for 2 18 BLs

I think Fi says that you should have 12-16 square inches of port for every cubic foot for any of their subs. Which means you should have 178.8 to 238.4 square inches of port for your 14.9 cube box. You have 56.52 square inches of port. Now, you do have aeros, but still, I think you should have at least 4 6" aeros.

Well, here's the deal guys. I've unhooked both bass knobs from the amp as of now. The reason is because now when the subs are playing bass notes from just a normal song, it will hit hard, then sort of just go back and forth, kind of like hitting and missing bass notes( all of this is after the bass knobs have been unplugged). But it does this when the bass notes are still being played in the song, not just randomly after bass hits. Right now the bass boost on the amps are half way up(if I turn them all the way down, I can have the gains cranked and nothing will come out of the subs, so they have to be set half way to even get the subs moving). I've checked the remote wires going to the amps and they are fine, but I think the problem is the rcas. The rcas we are using are pretty thin Schoche rcas, but we are going to replace them tomorrow with some pretty beafy ones that deffinatly won't have signal interference. Do y'all think this is the problem, by having thin rcas, or do you think it's something else.

I really need to know something soon!

Thanks.

The bass boost on the amp and the bass boost remote are basically the same thing. Please don't use either. Bass boost will clip the signal and kill your subs.

The bass knob is just a gain knob, it just cuts the gain as you turn it down. Nothing more, bass boost on the amplifier itself should not be turned on. I would assume as is the case with most hifonics amps that I have used that you will have to run the gain slightly over 1/2 way to achieve the amplifiers potential. Check it with a dmm to be sure like you should anytime you set up an amplifier. Make sure the low pass and sub-sonic are set correctly as well. Low pass around 50-80hz sub sonic at or just below tuning to be safe......

Bass knobs are not always gain knobs. Many cheaper amplifiers that I have seen are bass boost knobs. Make sure that it is not a bass boost knob before you turn it up.

The sub setting on the hu is also a boost. Don't use it. Always try to keep your settings everywhere as flat as possible. Don't turn your hu to minus anything either. Going + or - will distort or clip your signal.

Youll just be running the gain up way higher since your input voltage will be much lower, +15 on this setting is not going to distort the signal going to the subwoofer amplifier.

I always thought it was weird. If I left everything flat, and even if I put the gain up all the way on my 3000 watt amp, my 200 watt subs (they're just temp til thursday when I get my recones) would hardly bump. But when I turn on the MX setting, they would sound normal. Now I guess I'll turn off MX and turn the subwoofer setting to 15, and control the gain from there. Thx, I could never understand my Alpine deck.

The box isn't tuned to 25hz, I think it's actually tuned to like 35hz. The reason he hits that low is because his resonant cab frequency peaks at 25hz, which kind of ***** because he's not going to get much louder than a 145 unless he upgrades subs. Hold on a second and I'll get pictures of the truck.

Btw, he spent $8,000 on the whole system.:crazy:

Well, the kid with the ranger isn't to worried about whats on the meter, but he wants something over 150, which I think he will easily get. I won't get the truck till thursday afterall, so I won't have videos till friday. But we found out the problem with the subs fading was the ground was bad, so once we fixed that, it was all good. And, since it was absolutely pouring rain outside, we pulled it inside the flooring store we work at, and it shaked the place. We are pretty excited to get it metered, because the next comp it this sunday, so numbers will be posted sunday night if possible. I still need to do some final tuning to get everything right, but it is still insanely loud. He's easily the loudest in our area.

And to pd8731, this kid doesn't do the smartest things sometimes. And the funny thing is, he is going to spend about $2600 more to change out the JL 1000/1's and get 2 powerbass xa3000's,and put in a line driver to control the bass frequencies of songs.

He also entered the Extreme class where they put the mike outside the drivers side window and hit a 131, which the guy told us was extremely good.

Yeah, that's what we thought. However, we got the amps clamped so see what the impedence was coming from the amps, and it was about 4.8 ohms of power (930 watts) going to each sub.

Sorry but amps have little to do with impedence rise. The box is the main factor, which tells me the box is a little too big. However, Nick at Fi said that he has gotten the highest numbers with the least amount of "real world" power. And I honestly don't care if you did a 149 with 2 type r's, because numbers are all box dependent. Hell, Alan Dante just did 181 with a single DD Z series 18. But then again, his whole car is lined with concrete. So, yeah.

bigbud747
05-20-2008, 09:51 PM
Well here's what I think, but I don't know if this would work. Since the subs are D1's, could I wire them to the amp for a .5 ohms load, but since the imp rise to so much, should it level off to about 1.5~2 ohms, and not hurt the amps? Because with the subs wired to 2 ohms, the amps are only putting out about 4.8 ohms of power.

Lil Poot
05-20-2008, 09:57 PM
yeah you'll always have impedence rise, DCR is basically just a reference point. when an amp says it's 1 ohm stable, it's talking DCR, which is just what you read by checking the voice coils resistance with nothing hooked up to it. nominal impedence i think is another term for that. i wouldnt recommend dropping any amp under 1 ohm unless you know the amp will handle that, and you have plenty of current to feed it. i blew up my 200.1 because i didnt have the current for it, and i had 2 yellowtops and a 240a alternator with 1/0 gauge big 3. i was just bumping it too often, asking too much of it. amp used to get hot as ****.

with my kicker at 1 ohm, it barely heats up at all and is much easier on my electrical system. i'd be looking for something like an ia 40.1 if i were you. i hear the stetsom amps handle <1 ohm loads without too much trouble. american bass amps are supposed to be great for those loads, but i didnt have very good luck with my 200.1. the old 150.1's are supposed to be animals that low, but aren't quite as big as you're looking for.

bigbud747
05-20-2008, 10:03 PM
But since the amps wouldn't actually see a .5 ohm load, would they be fine, considering with imp rise they would be putting out about 2 ohms worth of power?

And, he definately does not have enough money to buy different amps.

Blove1991
05-20-2008, 11:05 PM
I think that just because of the rise doesn't mean the amps will always be around 2 ohms they're will be time periods where it drop down to .5ohm IIRC

Well, it took 3 days to make the box, seal it, and carpet it. Then a day to lay out the wires and sound deaden everything. Then probably another couple of days to get everything in and hooked up.

I would really like to get an answer fast on whether I can wire the subs to .5 ohms. I don't see why not, because once the subs start to move, it's going to raise the impedence in the box, and the amps won't technically be putting out .5 ohms.

Yeah..warranty usually doesn't cover abuse or using it at a load below its rated capabilities. Dont get me wrong, it might work fine, and I suspect it will. By no means, though, do I guarantee it to work flawlessly.

Also its pretty hard to get loud in a truck without a full blow through. There just isn't enough room in there to get loud legal with a regular set up. Outlaw or with the cab not sealed is another story, though.

talking about dropping the hifonics amps to .5 ohm nominal? i wouldnt without a very strong electrical. it will be a lot different than 2 ohms would be. it shouldnt hurt to try it, but, go easy on it for a few days and gradually increase the volume. watch your voltage, check the amp for heat/etc. ventilation is a must, but should be pretty good with the windows open.

if you find that they seem to be pretty stable, you still aren't going to want to drive around slamming full tilt everywhere you go, especially not when you're slowing down/stopped. hard on the old charging system, and they wont like to see low voltage.

Well, I believe the plan is to wire the subs to .5 ohms and see how the amps does. And, we might be getting 2 more aero ports. The aero ports alone should be a pretty big gain by themselves, but having the subs wired to .5 ohms and saying the box makes it rise to 1.5 ohms, each sub will be getting about 2500 watts, which should make them pound pretty good.;)

If you think that box will make the impendance triple than you are retarded.


The box alone will not make the impendance rise that much; maybe to one ohm, but certainly not from .5 ohms nominal to 1.5 ohms.

bigbud747
05-21-2008, 11:36 AM
Well, lets see here. Wired up at 2 ohms right now, we saw it rise to almost 5.5 ohms at one point. 5.5/2= 2.75 times more. I didn't know that 2.75 was so far away from 3 :rolleyes:

that was a pretty retarded post. resistance is all over the ****ed place when you play music. .5 to 1.5 is perfectly reasonable rise for test tones. it changes with the sub, frequency being played, enclosure, vehicle, windows being up or down, hell probably the air pressure/temperature, all types of variables.

05-21-2008, 03:11 PM
Temperature definitely plays a role, or at least the temperature of the coil. As it rises, it raises the impedance as well. Another thing, Id make a false floor, make the bottom of the box flat, and put the aeros across the top. It might not be that much of a gain, if any at all, but Ive had some bad luck in the past with odd shaped boxes and misplaced aeros..

You should have just gotten good amps to begin with, and the proper impedance subs. I would never trust any Brutus amp with .5 ohms.

We were actually going to go with just one big amp, so in that case we ordered the subs right, 2 D1's to run a 1 ohms load. However, plans changed, and we went with 2 seperate amps, so therefore we can either run them at 2 ohms or .5 ohms. If we would have ordered D2 subs, the only imp we could run them at if an amp went to each sub would be either 1 or 4 ohms. So I think either way, we made the best choice in ordering subs.

Sorry, but we aren't going to that one in springfield. He is however planning on going to the finals in springfield. With the way gas is, he doesn't want to make too many trips that far, since it is about 2 hours there from here. Also, this will make kind of an update: We are making another box that is 9.5 cubes after displacement, with a slotted port that is 135 sq. inches tuned to 34hz, and make a front flush mount piece that will also be a wall, so you won't be able to see anything past the box. The box alone should gains us something on the TL, and making a wall this time will make it even better. Our plan is to not carpet the box, but have the wall carpeted in some lime green carpet ( still not sure on whether to do this color of hot pink, and since we work at a carpet store we can get carpet pretty cheap). I want to hear you guys responces on what we're planning to do. We probably won't start the new box build for another couple of weeks so I'm open for opinions.

He just wants something completely off the wall. But, since he's the only one in about a hundred miles with anything like his setup, he's pretty much covered on being the baddest/loudest system. What really ticks me off is theres a kid in town with 4 W7's in a blowthrough (the one I posted pictures of). He just replaces the 2 1000/1's with 2 Powerbass XA3000's (we'll see how long them W7's last on that kind of power:cool:) and everybody around here thinks that it's the baddest system in the entire universe just because he has 4 W7's and everybody around this area thinks that w7's rule the world. And it really makes me mad when we put in hard work to make this system ( which is still louder that the 4 W7's) and that kid spent $10,000 to get his stuff done by a stereo shop and now everyone around here thinks the 18's are weak compared to his 4 W7's. :verymad::verymad::verymad: I just hate when a subs name comes into play more than the performance of the sub.

And I think at our employee price we can get it at $11 a sq. yard. This is the link to the carpet we're wanting to get. It's just something fun we're doing just because we can. :D

And the colors we're looking at are Sour Apple, Pink Taffy, or Bright Blue.

FINALLY!! Well, I spent about 2 hours last night cutting all wood and everything, and I made the port and painted it too. This morning I woke up at 7 and started getting to work. I took about an hour to assemble the box and get everything cut out. While I was doing that, Evan (the kid that owns the ranger) started on getting the seats pulled out and everything unscrewed from the box. After I got the box done, I helped him pull out the box and get a brace screwed to the back of the cab to screw the box to this time. Then, after getting the box secured, we ran the wire under the box (where it's cut out for the transmission well) and got a piece mounted ontop to act like a wall (it was gonna be too much of a p.i.t.a to make a whole wall piece). Then after all that, we slapped on the CAMO carpet that we got from out place of work, which turned out pretty B.A. And I know this is going to be asked, but is was just easier to make a whole new box than try to modify the old one.

Box specs: 9.5 cubes after all displacement
Tuned to about 34hz
Port is 30" wide and 4.5" tall

Sound report: This setup sounds a lot cleaner than the other one ( probably because the other one rattled so much :) ). The lows aren't as good (but I they might be about the same since when we played a low note with the old box, all we could really hear was the center support rattle), but still very clean, and it is ALOT louder in the 42-46hz range.

Now, on to the pictures. I hope y'all enjoy.

did you hook em up at .5?

bigbud747
06-15-2008, 10:24 PM
No we didn't. But the wierd thing is, the subs don't seem to have as much excursion as they used to. Even on a really low song, they move about 3/4 as much as they did before. Would the fact that the port is more restrictive now, or could the impedence rise be even higher, therefore giving the subs less power? Because if that's the case, it wouldn't be hard to rewire them to .5 ohms just to see what would happed. And if we did, by turning the gains down to compensate for more power make the amps run more efficient?

Box looks good. Next time you build a box though dont put a screw so close to the end of a corner. Looks like all your corners have splits in em. Other than that looks to be loud, especially with the port right at your head.

iamamp3pimp
06-15-2008, 10:39 PM
no they are gonna run less efficent iirc.

they may not move as much because the other ports were more restrictive.

when the ports are too small, or the box is sealed, the subs move a hell of a lot more.

thats why they dont move asmuch now, and its louder to you.

just a port doing its job.

Just an update on this beast. I'm going to redo and strengthen the center brace (2x10) so it will stop rattling and when this kid gets his stimulus check in, he's gonna buy a big alty so the volts won't drop as bad( right now at full tilt the volts drop into the 10 range, so it isn't near as loud as it could be). Here's a couple of more pictures from this morning when I took it for a short spin, and a teaser video to get y'alls interest.

Yeah, right now it's alot louder than the old setup for about 5 seconds then the volts drop down to about 10-10.5 so the subs aren't getting very many watts and the loudness wears off. But, once he gets a bigger alty, the volts should stay pretty high, which will equal a louder system. Does anyone know where he could get a good new alty for this truck. I think he wants something in the 200 to 250amp range, and if he can find one cheap, maybe a 300amp.

I guess I don't understand how a battery charger will help if I charge it once a week.

bigbud747
06-17-2008, 05:44 PM
I think I said this in an earlier post but, we ordered dual 1 subs because he was planning on getting just a single big amp, but that didn't work out because he didn't have the money for what he wanted, so we just decided on 2 amps that would do pretty good at 2 ohms. And with being rated at 1700 rms (probably only putting out 1500) at 2 ohms a piece, these amps were hard to pass up at the price ($450 each brand new through sonicelectronix).

Ok, thanks. He's coming over to my house this sunday and we're going to add another front piece to the box, put (laminate) 2 more 2x10's to the existing 2x10, and put 5 bolts through the bottom of the box to secure it to the truck (the back brace I made broke :( ). This will greatly strengthen the box, because right now he can't turn it up or else it would probably rip the face right off the box. If these upgrades don't work, I won't know what else to do to brace the box. These 18's have more moving power than I originally thought.

You should make lots more power at 14 volts coming from 10, which personally I wouldnt run them at 10. anything.... You could fak up your carputer with voltages that low.....

Get some deep cycles batteries and start checking locally for a place that can rewind your alt to make loads more power, should be a lot cheaper than the irragi, ohio generator, ect options.

Looks extremely loud, most I have installed is a 15" O series Eduh sealed on a NinE.1 in a ranger extra cab and the low end would knock your hat off, but that just looks fun as hell.

Watch the low voltage the amps are gonna be hating it too..
Try the battery charging option just to get you through the week... Hopefully his check comes soon.

Yeah, because when I first crank the system, the volts are at about 13-13.5, and it is loud as fack. But then, once the volts drop, it doesn't get very loud, so I'll try the charger trick for a while till he gets his check in. He's actually calling around right now and getting prices on getting his alternator respooled. The only thing I'm worried about right now is I think he has an 80amp alternator now and I'm not sure we can get his alty respooled over anything bigger than 140 amps, but maybe I'm wrong.:confused:

140 amps would work...

Yeah, because when I first crank the system, the volts are at about 13-13.5, and it is loud as fack. But then, once the volts drop, it doesn't get very loud, so I'll try the charger trick for a while till he gets his check in. He's actually calling around right now and getting prices on getting his alternator respooled. The only thing I'm worried about right now is I think he has an 80amp alternator now and I'm not sure we can get his alty respooled over anything bigger than 140 amps, but maybe I'm wrong.:confused:

If no serious electrical upgrades are made soon, I would definately adjust the gains on the amps so that they arent drawing enough current to kill the electricl. It will keep you from doing any damage to anything and possibly having to replace an amp.

Well, I've got some extremely good news. There's an electrical shop that works on electric motors and pretty much anything electric, and they can respool his alternator to 200 amps( they actually said they would just put new insides in the alternator and make it a 200amp alty). The best part is, it will only cost $80:eek:. I talked to the kid that owns this truck, and I said even if if only did like 175-180amps, $80 is a hellofa deal. So, he'll send his truck down to these guys in a couple of weeks to get his alternator "respooled". This should help his voltage problem alot. :D

06-19-2008, 10:28 PM
nice info. You need to ask him how much will the alt do at idle. If the alternator does the rated "200amp" at 4k RPM, it owuld be useless for a daily setup. $80 is hella cheap, so you might wanna confirm with him if he can get it benched with papers to show those results

How would I get it benched? Just take it to autozone of something and them hook it up to a machine?

Just an update on this beast. I'm going to redo and strengthen the center brace (2x10) so it will stop rattling and when this kid gets his stimulus check in, he's gonna buy a big alty so the volts won't drop as bad( right now at full tilt the volts drop into the 10 range, so it isn't near as loud as it could be). Here's a couple of more pictures from this morning when I took it for a short spin, and a teaser video to get y'alls interest.

Yup, the old 95 amp alty is still kickin. After seeing a memphis 4K in his last setup, and now seeing about 3000 or more from this setup, it's still holding up well. But, after he gets back from his trip he's going to have some people redo his alternator and make it 200 amp.

Well, he actually has 5200 on tap if he blows these subs and can wire them to 1 ohms next time. So in that case, these two amps were a better deal than a sundown 3000, and he's got a 1 year warranty through sonicelectronix on these amps too.

Yeah, going from a 95 amp alty to a 200 amp alty will be a great improvement. And for only $80, I might send my alternator down there just for fun because trying to jump start a 3/4 ton diesel truck every other day doesn't do well with my stock 115 amp alternator (volts drop to about 10.5-11 when trying to jump start that truck) . Lol. Just curious, can u tell me what the volts on this truck will be like after putting in the 200 amp alty, with 4 batteries, and running about 2500-3000 watts, or is that something you really can't tell till I get it in and test it?

2500-3000rms? Aren't you running those amps at 1ohm? .

and no, theres no way you can tell how much voltage drops your getting. You can tell how much amperage draw is taken, as well as the amplifier's efficiencies. But with those amps running at 1ohm, i would highly look into a 300amp alt. Easier on your electrical system, along with giving the appropiate voltage for your amps.

Lol. Why is that? It's not like the kid was retarded or anything or he actually believed it. Now since I pretty much screwed the box to (through) the back of the cab, the back windows don't flex much at all, unless I'm playin a note around 40hz. The box is solid as a rock and doesn't move at all. Now I just wish I had an extended cab truck so I could put a system like this in it, except I would do something like 2 soundstream xxx 15's off about 8000 watts. Then I would have to buy a big toolbox just to put all the batteries somewhere. :D

I actually got that idea from seeing a picture of a guy with a 1500 chevy that had a blowthrough design a year or two back. When I seen it i thought that it was a pretty good idea to stop flexing, and a cheap idea too. So, when I put this system in I asked the kid if he wanted to do it, and since he trusts me:D we put in 20 tennis balls behind the cab. I think the total cost of tennis balls was like $10 or something like that. So if your truck flexes like a mo fo then I would highly recommend doing this mod, because Dynamat will not keep the back of your truck from flexing as well as tennis balls will:). lol.

Well, here's the deal guys. This kid just got back his memphis 4k (from being worked on because of low voltage problems with his old setup). I think we're going to hook this thing up if we've got the time to see what the subs will sound like with that one big amp. My question to you guys is, do you think this amp will be better/more efficient than the two hifonics brutus amps he's got now? With an estimated power of 4000 watts at 1 ohm (maybe more once we get the bigger alty and hold a constant voltage), do you all think it will power the subs as good as the hifonics amps (~1700 at 2 ohms x2 for both amps, so about 3500 watts)?

Ok. Well, like I said, after he gets the new alty put in (should be a week or two maybe sooner) we'll throw in the 4k. We shouldn't have much voltage problems at all, so the Hifonics amps might be gettin the boot for the 4k, but who knows. It's a lot easier to tune one amp than trying to match 2 to the same output. I'll get pictures of the 4k in a couple of days. I've only seen it one other time, and man is that thing LONG!!!:eek: It'll match nicely with the camo, and sittin right at the bottom of the box all layed out. :D

If you read the whole thing, then you would see that score was with the old box. I have yet to get this thing metered, but I think it'll do close to, if not over a 150. The mid and higher frequency bass has picked up a lot. And the area at which it peaks at has a lot to do with the vehicle, not just solely on what the box is tuned to. And he had the memphis sent off about 4 months before we even started this build and he didn't have another amp, so he just bought these for a **** good price to power it. And now that he'll be getting a bigger alty, he shouldn't have any voltage problems, which was what caused the memphis to fail in the first place.

Very nice vids! Love the glove box flex..

Right now with his stock alty, I'm guessing we could burp a 149 maybe 150 but it wouldn't be for long since the volts drop pretty fast. Once the new alternator is installed (It's only going to be a 160amp until he can get enough money for a bigger one, but for $65 you can't beat 160amps) and his memphis 4k put on the subs, I'd estimate a 151 or possibly a 152. But who knows, maybe the 155 mark is closer than I think. It's just crazy loud now, a lot louder than the old box, which did a 147.6.

I think the problem is just low voltage, but once he gets his stimulus check in (shouldn't be much longer) he's probably getting a 200 amp alty from excessive amperage.

I believe its the mounting location that caused the amp to fail. I have had this situation with almost every hifonics amplifier from hifonics bxi1606,2006, hercules, 2607, and the XXV Colossus. They seem to be very senstive to vibration. In your case, I'd assume vibration was the major cause.

Well, he said he heard something pop. I got to his house like 5 minutes after it happened and when we plugged the rca's in to play the sub, the amp just started rolling smoke out of it.

Is a d3100 just a big yellow top battery, or something else like kinetic? And he's like me about who sits in the truck, and nobody that smokes can come close to the truck just because he hates the smell of smoke.

No they don't the newer models are very efficient, and for almost 200$ more i can see that amp being more effiecient, but not that much for 200$ you could almost get another amp

Just a little update on whats happening. We are ordering a 250 amp alternator from mechman.com in the next week or two, so voltage shouldn't be a problem anymore. He's also going to put in an optima yellow top under the hood to help out voltage until he has the money to get a really good battery. And, this weekend he's going to see his uncle and pick up his 4k, so I'll have pictures on here sometime later next week.

And on a side note, I bought a little over 18 feet of 1/0 welding wire from a kid that just had it laying in the back of his truck and wanted rid of it. It looks pretty much brand new. The best part is, all 18 feet just cost me $20!!:eek: It's not often a person stumbles into a deal like that. Lol.

not all "remote knobs" are remote gain knobs

set the gain on the amp, and the remote gain knob can not go over that.
