View Full Version : Help a noobie out

01-06-2012, 04:06 PM
Maybe u guys can help me out a lil bit better. I have a Ford Escape 4 cyclinder wit a small battery smh...but i added the battery of an Grand Marquis to help out with power. Im adding a Yellow Top pretty soon and upgrading my Alt a lil bit later....

I currently have an Hifonics bxi2608 but i plan on upgrading that to better suit the sub i get. budget i dnt wanna spend no more than $600 for my amp.

i want 18'' sub to be between 2000-4000 rms.... the sub would b a daily and will b ran at 1ohm or lower. Sub will be in a ported box.

can sumbody help me out wit my setup up or where to start????

People were just giving you **** man. 20 cubes? Think about it..... That's bigger than your whole Escape, LOL! There's a few 18's for sale on here. Look around. And I think your amp will be plenty to push just about any 18. You can upgrade if you'd like but going down to lower than 1 ohm on a daily drive setup is kind of foolish to me. By the way, most 18's you'll probably get by with 5-6 cubes.

01-06-2012, 05:25 PM
thats a good one lol .....i dnt want to under power the sub and blow it.....yea it'll b a tight fit but i can squeeze it in witout losing my back seat with the rite box

what would u sugguest for a daily drive setup then

01-06-2012, 05:29 PM
Why an eighteen if I may ask?????

Why an eighteen if I may ask?????

Same question I had. And you'll NEVER blow a sub underpowering it. I don't know who told you this but it ain't true. I think if you're going for loud and taking up the same space with the amp and the budget you've got you could do more damage with a couple 15's. But that's just me. 18's are kinda playin' with the big boys. My suggestion to you is go over to the subwoofer classifieds and pick out an 18 if that's what you're stuck on or buy one off Ebay or whatever and talk to pro-rabbit or ram on here. They'll build a box to your specs (space, what you like to listen to, etc....)

01-06-2012, 05:38 PM
Come on man, I rock 20 cubes in a VW beetle..... ;)
Seriously, I might as well say DC Audio before some other person says it.... What are your goals? SQ, SPL? You can get some seriously good sounding subs in that power range and you can also get some junk depending on your overall goals and buget. The LMS Ultra 18 would be one of the best imho,
TC Sounds LMS Ultra 5400 18" DVC Subwoofer 293-666 (http://www.parts-express.com/pe/showdetl.cfm?Partnumber=293-666&utm_source=googleps)

01-06-2012, 05:49 PM
And the above mentioned sub from parts express is in your price range. And seeing as how your Hifonics amp pushes 2600 rms @ 1 ohm you should be good. I'm sure the sub can take more but for now you're going to want to spend that last 500 bucks you got on an enclosure for that beast!

01-06-2012, 05:49 PM
find two used sa12's or sa8's. big subs dont always equal big sound....

this^^^ what he said....

01-06-2012, 06:21 PM
my 1st setup was 4 MA Audio 15's per sub 800 Peak 400 RMS i dnt know how i blew them but they fried quickly.....
2nd setup was 2 Alphasonik 15'' 900 series Mayhem per sub 5000 Peak 2500 rms....
3rd setup 3 Power Acoustic 12'' 800 Peak 400 rms....
my 4th and last setup was 2 ssl 15'' 2400 Peak 1200 rms but these were completely OVER Rated smh waste of money.......

with every setup up i had i used my hifonics 2608 wit an extra battery from a Grand Marquis w/ a 2.5 farad capacitor to help power everything

so now i want to get one solid sub

i just dnt want to under power a sub and blow it so if i have to upgrade my amp i will

i figure i need to upgrade my power supply

01-06-2012, 10:46 PM
UNDERPOWERING A SUB WILL NOT BLOW IT!!!!!!! however, not sending enough power to the amp will bow the amp... so upgrade your electrical, then go find two used sa12's, a nice amp, and a good box and you will be very happy...

01-06-2012, 10:51 PM
I'm starting to think he might not be able to be helped. You would think he'd have one buddy around that would know WTF they were doing? Sigh....

01-06-2012, 10:56 PM
Maybe the boss 18 in 20 cubes is his best bet.... tune the port to 300hz.

01-06-2012, 11:00 PM
LMFAO! You're killin' me! What part of Minnesota by the way? I've been there a couple times. Grew up in Milwaukee and went to see a couple Packers/Vikings games at the dome. Ya dare hey!

01-06-2012, 11:02 PM
I live in Mora, about an hour north of minneapolis.

01-06-2012, 11:07 PM
I miss the snow man! Not so much the freakin' cold but I do miss the snow. My parents are still up there. Said it's been pretty nice lately....

Anyway, so 18" Boss (Chaos or Phantom) in 20 cubes at 300 htz? Seems about right.... Although if it's the Chaos he could probably get away with 18 cubes.

01-06-2012, 11:15 PM
yeah 18 cubes and a phantom 5000D... 5000 watts max but knowing boss it probably puts out 30k rms....and yes, no snow =no sled=:suicide:

01-06-2012, 11:20 PM
You're probably right. He could look at Lanzar Max 18's well. With one of those ******* Vector amps! Hell yeah! I gotta stop. He makes me feel ashamed of myself.

I know I'm sounding like a skipping CD, but the TC Sounds LMS Ultra 18 will be the BEST sounding sub for less than $1K (that is currently available). The most linear, low distortion, high excursion sub. Wish I could afford one, its what I would buy in your shoes, obviously. ;) Everything else in a 15 or 18" sub will sound "sloppy" compared to this....muddy would be a good word.

Loud and big are never as good as clear and accurate while being loud. I've heard some seriously loud systems that sound like total crap and other systems that were just as loud and sounded 10x better. Its all in the equipment and install.

For the small space you have your better off going with a single 15" than an 18. Have a box built right and it'll get just as loud as you think you'll be with an 18. And dump that stupid capacitor you said you have, upgrade your electrical system before you spend more money on your system. The Big 3 is the place to start, buy some Knukonceptz 1/0 wire for cheap and do it right. DC Audio, Sundown, Incriminator Audio, whatever you can find thats within your price range, they're all good brands. And have someone that actually knows what they're doing set the gains on your amp with an O-Scope, chances are thats why you blew your old subs.

01-07-2012, 10:51 AM
Thanks alot everyone im goning back to the drawing boards and starting from scratch....

this time imma do alot more research on wat i buy

once again thanks for all your help

01-07-2012, 10:17 PM
First off, I bet you are blowing subs from cranking the gains on your amp. Causing clipping and eventually frying your subs.

Second, you need to do some reading. Lots of it actually. Understand the fundamentals of watts, amperage, voltage.

As for what gear to buy....none. Not until you figure our how the system works. Even with the best gear in the world, if not set up proper, it will sound like crap and fry.

01-08-2012, 12:28 PM
yea i honestly never took the time to learn about amperage, voltage, and watts.... so i found a site that teaches

Basic Car Audio Electronics (http://www.bcae1.com)

if u know of any other sites that would be great

01-08-2012, 12:31 PM
the12volt.com has a lot of good resources. I would also suggest reading around on here but sometimes its hard to tell what info is accurate and what info is skewed, especially when you are a noob. I spent a month installing my first setup, each day I would look up something and then go outside and do it. Trial and error is a good way of learning but you need to know the basics first

01-08-2012, 03:20 PM
Yup, bcae is a good site to start with. I would also research "setting gains", "rms vs peak" and "clipping". Use the search here and google.
