View Full Version : Sundown Audio Nightshade 18'' -- AQ2200 >> Truck Build

- Nightshade 18'' with new aluminum pole w/ 4 spiders (2 soft, 2 hard)
- AQ2200
~4.5^3 @ 32hz (after displacements)
The desigin comes out to 5.5^3. With sub, port, and bracing I think it will be around 4.5.

http://i355.photobucket.com/albums/r475/BobbyGedUp/box-1.jpg?t=1261269997

The port may have to be resined up for extra strength since its weaker than aeros. How should I brace it? Ive never have done tube ports before, so I don't know how I should brace it and attach it to the box, etc. Any help on that would be very useful.

The tube is 8'' diameter and I'm cutting it to 24'' for 32Hz tuning. I was told this will take up about .5 cubes? Its 48'' long so I have plenty to work with.

I don't know how to do the math, but how much depth for the sub will I have with that box design? Since I have the aluminum pole I dont need to have space for the pole to vent (thanks jbizzle)

Just did the math and the sub should fit fine.

I was hoping I could use threaded rods for bracing but I dont think that would work well on the angle.

Alrighty than. Does the sono need to just be sealed in the cutout and have some bracing inside the box? I was just going to design something for it to rest on.

12-20-2009, 01:20 PM
Lol this plan isn't going to work. I just made a little mock up and its a fail. No way this sub is going to fit unless I have a stupid big bulky box and have no room for anything else. Blow through isnt an option...so I dont know what do to other than going to smaller subs like 3 tens. I think I'm going to have to trade/sell this baby away...

you can use the 18 in 4.5 cubes, 3 10s are probably going to need a bigger box than that.

yeah i know but the box design I have wont fit the sub it at all. Its not close to deep enough. I would have to build a big *** wedge box and leave my passenger seat screwed and middle seat out.

Bobby322
12-20-2009, 01:38 PM
I have the space, its just the depth and size of the sub thats killing me

Bobby322
12-20-2009, 06:11 PM
Buuuut wait! Just got another box design done. I think this one will work...it may still be cramped but oh well. It came out to 5.75^3 before displacements. After sub (.25), port (.5), double baffle in front (??), and some bracing (??), I hope im under 5 and close to 4.5 cubes.

http://i355.photobucket.com/albums/r475/BobbyGedUp/box2.jpg

http://i355.photobucket.com/albums/r475/BobbyGedUp/100_0405.jpg

I just got the peices cut except for the side peices. I have the double baffle clamped and glueing right now.

Is there a certain amount of room the end of the port needs to have away from the motor of the sub in the box? The port will be going a little past half way in the box, and Ill try to get the sub as far over as I can. Im still not sure how im going to go about bracing and putting the port in.

As far as im concerned...im getting this bich in there before I give up on it. I still have a whole sheet of mdf :D

x2o
12-20-2009, 06:13 PM
Haha glad to hear it may work, as far as the port being away from an object, I believe it like half the port diameter, so for you it should be 4" away. This may be wrong as I'm just going off of what I may remember though.

You might wanna figure out the box size before cutting that port though.. lol :P

Bobby322
12-20-2009, 06:15 PM
Alright thanks. I just dont know how much displacements everything is going to take up. I know the sub is .25..but how much exacally is the port going to take up? I put in .75 for the thickness in the box calculator for the wood, so how much will the double baffle up front take up? I plan on adding as little bracing as possible.

KHARPS
12-20-2009, 06:19 PM
length of port x OD of port x 3.14 = X
Then divide X by 1728

Bobby322
12-20-2009, 06:24 PM
^^ thanks. Based on that and with a 24'' long port its only .35

Bobby322
12-20-2009, 06:26 PM
also, is it possible for me to port out of the top? Or will the slant have an effect? I would have to leave some port sticking out because the box is only 21'' tall

Bobby322
12-20-2009, 06:33 PM
okaay. So according to my calculations, the extra layer of wood for the double baffle will take up .41 cubes.

Sub - .25
double baffle - .41
Port - .35
bracing - ??

right at 1^3 without the bracing factored in. So that leaves me at 4.75^3 before bracing displacement.

I plan on adding some sort of " U " for the port to rest on. Think the port will need to be between 22'' and 23.5'' according to the 12volt port caculator.

Do I need to factor in the .75" of wood that the port goes through? So should I add .75'' to whatever im cutting it to?

Spooney
12-20-2009, 06:36 PM
length of port x OD of port x 3.14 = X
Then divide X by 1728

Wrong.

Its half the diameter of the port(the radius) squared(so approximately 4x4) x 3.14 x the length of the port divided by 1728

KHARPS
12-20-2009, 06:36 PM

The slant won't affect it as long as the port doesn't touch the baffle. Make sure you leave a port's width away from the bottom of the box though.

Bobby322
12-20-2009, 06:36 PM

Think it will be noticably louder if I port up compared to the side?

Wrong.

Its half the diameter of the port(the radius) squared(so approximately 4x4) x 3.14 x the length of the port divided by 1728

That would be .66 cubes. I used 23'' as my port length. Which one of you is right? :D

Displacement is how much room something takes up. I would think you would use the entire width and not just the radius, I could be wrong though.

no prob. I have 4.4^3 after displacements, not including bracing.

Think Im going to have to port through the top and leave some port hanging out to save room.

Decided im porting out of the top of the box. 11'' in the box, and 11'' out. Box is 5.75^3 before displacements.

sub - .25
port - .32
double baffle - .41

4.75^3 after those displacements. Ill try to brace strong but with as less as I can.

RAM_Designs
12-20-2009, 08:12 PM
you can use the 18 in 4.5 cubes, 3 10s are probably going to need a bigger box than that.
Not really, since a normal 10" sub needs 1-1.5ft^3 each, and you can get away with less since he'd be using a common chamber.


length of port x OD of port x 3.14 = X
Then divide X by 1728
Nope.


Wrong.

Its half the diameter of the port(the radius) squared(so approximately 4x4) x 3.14 x the length of the port divided by 1728
Yes!

Nope again.

I'll use a mixture of both liquid nails and wood glue. Some say the liquid nails are better, some dont.

If you must use the liquid nails id just do wood glue on all the joints and then use the liquid nails on the internal seams to make sure shes all sealed up

How should I make the flares for the port? Does it NEED them? I read it makes it more efficient. I will eventually go to aeros probally, but for the time being what can I do?

Bobby322
12-21-2009, 12:53 PM
Lol so i remebered seeing a thread a guy posted where he made his flares for his sonotube. He might have had platic plates. Well I just made some ghetto fabulous flares out of some paper plates. I doubled 'em up and glued the hell out of them. Worth a try? Will be getting aeros in the future.

12-22-2009, 10:51 AM
Another question..

I used this box calculator http://www.the12volt.com/caraudio/boxcalcs.asp

When I put the side peices on should they go flush into it or should I just slap it over the baffle and all the sides. If I did that, then my total length would have 1.5'' added to it. Kinda confused here. If I put the peices flush, then I wont have to add that into the inside total volume?

sorry kinda hard to explain

Bobby322
12-22-2009, 08:36 PM
Just have to put on side peices and take the grinder to some joints and edges to smooth it out. Maybe ill spray paint it :D Think I should've gone with thicker threaded rod.

12-22-2009, 09:07 PM
Before I cut my port to length, Ive got some questions...

I dont know how this calculator does it http://www.the12volt.com/caraudio/boxcalcs.asp but instead of making the sides and top flush height with the back peice, I layed it on top. So that adds .75 to some of my dimensions. Do I re-do it in the calculator the way it is now? The top and side peices will be laying on top of the other peices, not inside it. How do I do this math?

Bobby322
12-22-2009, 09:52 PM
After the all displacements other than port (which I dont know what it will be) I have 5.38 cubic ft. How long does my port need to be @ 32hz? Port is 8'' diameter. I need some sticking out and cant figure out how much needs to be in

not bad for you first box. i have a couple of tips for you.Get yourself a nice strait edge and some nice screw type clamps. first measure from the side of the blade of the saw to the edge of the table on the saw. one side should be around 1.5" and the other should be 3.25" anyways clamp the strait edge down so you can run the table of the saw along it for a nice strait cut. if your right handed take back that saw and trade it for the one with the blade on the left side of the saw it will help a ton.(if your right handed) and last would be dont put screws right in the corners I always stay around 2" in from the corners.it will keep it from splitting the mdf

Bobby322
12-23-2009, 08:56 PM
ill look into that thanks. And yeah I figured out the hard way on splitting the wood on the corners.

RAM_Designs
12-23-2009, 09:35 PM
Pre-drilling with even the skinniest of bits will keep you from splitting the MDF while using normal coarse thread sheet rock screws. Nice job though, I imagine it'll be pretty loud.

Yea not bad for 1st box. +1 on the predrilling it works wonders. And as for not perfect cuts if there is a bit of over hang on one panel. Get a router with a flush bit it makes the world of difference way faster than sanding. But yea looks good

if you have some one with a meter cut off and inch at a time to it stops getting louder first find your loudest freq on a tone then test 2 to 3 hrz below and above that after each inch to see if your peek freq changes with the box tuning

you should be fine with the port length you have...tuned to about 31hz at what you have it at now...i wouldnt cut just yet...test first then cut if need be

id rather have something that i like the sound of rather than correct mathematically

you have a point...i just don't want my ears to let meh down.

31hz works for me..i like it low. I might need some extra 1/0 from my battery to amp and id rather get some 10 guage speaker wire. I have 28'' more of the tube left over and I plan on going with aeros later on

Fits pretty good, seats aren't too bad. The middle seat fits perfectly and has lots of room for the bichs. Battery fits nicely on the other side of the box, and the amp is going to be mounted on the top. Might go pick up some wire tomorrow and hook it all up. Local prices are ridiculous...$5 and $7 per ft for 1/0 at a few places.

12-27-2009, 04:57 PM
I tried like hell to take that back seat belt track off and it wouldnt budge. The bolts holding the peices on weren't coming off.

jbizzle
12-27-2009, 04:59 PM
Very nice, glad to see it worked out :)

Next time you build a box you can try to make it less deep and more wide to get more room behind the seats.

Bobby322
12-27-2009, 05:01 PM
Thanks, yeah I thought about doing that but I wasnt 100% sure how deep the sub would fit in. And if I made it extend across the whole cab, I'd have no room for the battery.

get some heat on them and use a torque wrench

Bobby322
12-27-2009, 05:51 PM
Ill try that but I used allen keys with the handles on the end and they didnt budge. They will strip before they come loose.

are they allen or torx?

CranberryYumYum
12-27-2009, 06:28 PM
they're torx that's for sure. all seat bolts are. you NEED the torx bit and a torque wrench or you WILL strip it, guaranteed. don't touch it without the right tools because it's a ***** and a half to drill out those seatbelt bolts

edit-heat gun? no, acetylene torch

Bobby322
12-27-2009, 07:43 PM
I thought they were allen but now I think about it maybe they were torque. I hope they arent too stripped

Bobby322

Pretty loud!

Just got it all in today...did 1 of the big 3's as well, alt to battery

It gets hella loud when I have driver door open. Def. doesnt like to be sealed up though. Still have to mess with tuning and all. Think my LPF and subsonic are off.

Ill get a vid soon

Bobby322
01-03-2010, 06:03 PM
Had to film with my 3mp camera phone sorry bout quality, still picked up some flex. Haven't fine tuned it yet, or experimented with many songs...just know this song is loud.

i think you dont have enough room man..get rid of the 18", get a NS 15" rebuild the box and youll probably be louder ..this is coming from someone experimenting with 15's 18's and ext cab trucks ;)

Not enough room as in my box is too small?

Toone
01-04-2010, 09:04 AM
dosent look loud at all but looks are sometimes decieving. try using a smaller sub / better port. for being tuned to 31 like you guestimated it was it should be moving alot more air than it is

Bobby322

You can't tell by watching a video online so I wouldn't be worried bout these guys saying it doesn't look loud.

Bobby322
01-04-2010, 09:44 AM
lol yeah. Just tested out some more songs, gets lots. Louder to ear and still moves air sealed up. Will upload vids later

basscort2009
01-04-2010, 09:50 AM
get a real camera man i wanna see some flex! lol told ya one 18 would be nice in that *****. 1 18 is the way to go. go big or go home. and props again for taking the balls to build your own box and not tap out and be scared. good work bro

statonburrell
01-04-2010, 09:52 AM
i agree I feel like it should be moving more air... is the sub brand new? not broken in yet?

canyouhearmatt
01-04-2010, 12:54 PM
what im saying is the sub is louder with the door open meaning his sub isnt getting enough air..either that being the box or the cab? im thinking if you drop to a 15" it will have proper air and move more air being more efficient.....am i making sense?

mazdakid
01-04-2010, 12:58 PM
How do you know how much air he's moving without being there? He bought the sub used.

on1wheel01
01-04-2010, 03:05 PM
Yea like said looks can be deceiving but a smaller sub would prob be better. Hell im in that situation myself but having a 18" NS sure is nice for de low lows

audioatg
01-04-2010, 04:31 PM
I think it looks good bobby32. I have a 18 as well. Think I might put in my truck. I have a dodge dakota ext cab. I know I have room. My box would be different then yours but how big is the box. I seen some flex as well with your setup. That door is moving. Now my 18 I had in my spl box didnt move that much air either. But mine was tuned higher then yours.

Looks good though.

jbizzle
01-04-2010, 05:39 PM
Glad to see its doing some damage, passenger door looks like it was taking a beating.

Bobby322
01-04-2010, 06:41 PM
thanks guys. I have a feeling my lpf, subsonic, and maybe gain are off. The gain control on the amp is kind of broken and it spins in place, so I dont really know where it is actually set at. It might be able to go higher... Some songs are much louder to the ear and move some air, while the low notes aren't as loud to the ear but move lots of air.

also, I dont think a lack of space of the truck for the sub is a problem because I've had a single 12 and single 15 in the truck and they both liked having a door or window open a lot better.

Its just your truck, most pickups don't like sealed up.

Bobby322
01-06-2010, 06:28 PM
yeah for sure. But I think my electrical needs to be beefed up majorly. I cant have my gain or bass knob up very high to where i want it without having the clipping light come on. I dont even like to see a flicker of the clipping light coming on so I keep it down. It gets HELLA loud when I have it up high but the knob indicates im clipping the hell out of it...so i keep it down.

Gotta finish big 3, another battery would help the most, and more runs of pos/neg and then I can crank it to its potential w/o clipping

KHARPS
01-06-2010, 06:31 PM
Leave bass knob off!

Bobby322
01-06-2010, 06:38 PM
My gain control on the amp is kinda broken...it kind of spins in place and does a full 360° I have it set on about the highest it will go but its not actually the highest because its messed up I beleive. Last night I had my cargo light on in the cab and it dims like hell on bass hits. My voltage gets high enough, just drops ez .

Bobby322
01-09-2010, 03:25 PM
So I unplugged my bass knob this morning, and holy crap its 10x louder! I dont get how its louder w/o it? Im getting WAY more excursion and its lots louder. I play some songs for a little bit and didn't smell any burning coil, so I guess im not clipping it (too bad)? I notice it eats up my voltage hella bad, even when driving so I turned it down when I noticed that. Any idea why this happened? Only benefit bass knob is giving me is clipping indicator if its quiter w/o it.

You saying its louder, we want proof!

If it doesn't get stinky, or get warm then its fine. Put your hand on the dust cap to see if its getting hot/warm.

Bobby322

Added the battery neg. to chassis wire on big3...just missing the engine to chassis now.

Here are a few more vids. Dunno if you can tell the difference from before but you sure can in person. Much more windshield flex and air movement...voltage still drops bad though.

See good flex towards the end on this vid:
