i just installed a set of street edge 200 watt 12's in a sealed box and it's to big for anyone to sit in the back seat. what kind of wood should i buy to build the new sealed box's. i would rather have the sub's away from each other than them being in 1 spot. FYI: the head unit is pioneer 200 watt's, pioneer 6x9's 200 watt's each, california profile msx 600 watt amp, street edge 12's in 1 sealed box rated at 200 watt's each. total wattage = 410. not bad for a small upgrade ....amp, sub's, box, wire kit out the door $200.00

Usually 3/4" mdf is ideal, if you use 1/2" you may need to brace it internally but you are not running huge power so either way should be ok.
Just make sure that you match the volume requirement for the subs other wise you will be disappointed in the sound.

1) Why move the subs away from each other? It is usually better to have them in the same plane and as close as possible.
2) Use 3/4" MDF.
3) As dwarren said, look up the specs of your subs so you don't make the box too small. It simply won't sound good if you cramp them.
4) Buy some stuffing for boxes. It will make the woofer behave as if it were in a slightly larger box.

Matting takes up space, it doesn't make the woofer behave like there's more. Matting would give you the opposite effect.
This is the product I mean:

in my experience matting doesn't really help at all, use 3/4 or 5/8 mdf,, what kind of a tool do you need to pull up that gard? isn't it just clips? ------------- Bad Boys Customs

by the way, you pick up that poly fill, or a.k.a pillow stuffing at most craft stores like ben franklins, etc.

I would rebuild your box using the subwoofer specifications. Use 3/4" MDF. Stuff the box lightly, 100%.

if i just pulled the 12's out and filled the box half way with poly-fill . would it sound better because i really don't want to rip apart the box . i do know it's built with a devider inside . these street edge sub's hit hard but i want to make em hit just a bit more .

the poly fill will not make a huge difference, but more important is the internal volume of the box, without a doubt. You might experiment with the poly fill as it is cheap.

Wait a second, your original post said you wanted a new box because your current box doesn't fit. Now you want to know how to make it "hit" more? Which one is it?
Also, poly fill will not make it "hit" more. Poly fill will increase extension and transient response slightly.
Decide what you want help with.

Maybe i didn't Explain myself to well . so excuse me for the 1st post . what i have is a sub box that is bigger and takes up half the rear seat in my ext cab truck . what want to do it is take the box out and seperate the sub's and put those in different encloser's so i can have room for passenger's in the rear . then i wanted to know if i can get more bass out of my sub's so they'll hit harder . since i'm running 2- 12's and pushing those with a 600 watt amp you figure they would hit harder . but they only put out 410 watt's . but i'm not going to waste money on poly-fill if they don't hit harder .

Well. No matter what step # 1 is to find:
a) how much space you want to get the subs down to; and
b) the specs of your subwoofer so you can decide how small you can make the box w/o it affecting the sound too much.
After you do all this you can worry about poly-fill. Forget it fow now.
Also, speakers don't put out watts. :-) The watt rating is just there as a guideline for how much power they'll handle.

kfr01 brought up many good points as always. I'd like to add a few questions which may help to be the deciding factor in whatever route you take. 1. What is your main goal out of your system? (I'm guessing an SQL setup by the sounds of it.) 2. What types of music do you commonly listen to? 3. What vehicle will this be going in? Always remember that mediocre equipment in a proper setup can sound better than high quality equipment in a horrid setup. Trust me on this one. Profile amps are actually pretty decent for the price. They may be considered lower line products, but they're fairly good on a budget. Answer the questions I gave you and we'll help you to get the best sound possible out of the equipment you have to use. That's what it's all about really. ------------- Dave

AudioBass12 What i'm trying to do is get these sub's to hit harder without buy more equipment . i'm on a very tight budget right now . The music i mostly listen to is heavy metal and country . This set up is already in my truck and it's a 94 silverado ext cab . i've got the box facing forward and the sub's are firing at the back of the front seat . Here is the size of the box : 26" L x 1' FT D x 15" W The box has a divider built in to keep the sub's away from each other . so i'm guessing the sub's are sitting in 1 cubic foot of space

If you're really wanting to get louder, Id suggest building a ported box to specs for either 1 or 2 of the subs you have. If you don't have enough room for 2 of them, one sub in the right enclosure could sound better than both in improper ported or sealed enclosures. Keep in mind ported enclosures generally don't sound as "tight" as sealed enclosure, but if you're lookin for loud then that's the way to go. Otherwise, just rebuild a sealed enclosure to specs and add polyfill.
