Here's the deal. I have a GMC 1500 extended cab. I already have 2 subs under the seats and I'm looking for somewhere else to put subs. Any suggestions at all?

Center console? I have 2 very shallow 8's you could fit in many places if your interested?

I'm not too big on the center console idea. I have considered it, but I don't really like it.

Backseat out, wall. Only way to get loud unless you do some cuttin (blowthrough)

Well behind the seats? Thats pretty much the only place unless you wanna start cutting and modding stuff...

That was my first option. Is it a real pain to remove the seat in order to do that? And how much room is there behind my seat?

Not much. A tape measure could probably yield more accurate measurements though.

And to daboy, I guess you're right. I just don't want to take my seat out and everything and then be like oh hell I can't put a sub back there. Do you think there is enough room for a shallow mount or whatever it's called?

what year is it? I have a 1999 and there is plenty of room under the rear seat to do a downfire or up fire box.

Theres room, it just doesnt sound that great. Even with polyfill

It's an 02. I already have 2 subs in a downfire box. I just like bass a little too much :D so I'm trying to get more. And what about installing another box between my existing one and my front seats? Has anyone tried that?

If I'm picturing my friend's extended cab correctly when I did his subs (under seat box but I mounted the amps to the rear wall). You should be able to fit some shallow mounts back there, pending on your box. If you build the box, with the proper measurements, you'll be fine. Trying to find a prefab may be difficult as it does need to taper pretty thin at the top. Don't quote me on anything here, just going off slight memory.

Well, your memory is better than my experience, considering that I had a friend put mine in and paid him like 50 bucks

I did a downfire and put a peice of mdf for the subs to reflect off of. Made a difference vs carpet

try raising the seat 4" and build a custom box,you'll get better output then

How the hell do I raise my seat? And does the board to help the sub reflect work because it a harder surface?

Right IMO the carpet absorbs some sound

This was what I was going to mention.I raised my rear seat with a bracket welded approx 4.5 inches, and still give plenty of head room for passangers seated from the deck.I was able to build a custom made front fire ported box on each side of the trans hump for a pair of 900 rms dvc4ohm subs@ a 1ohm load.Now Im taking back seat out, and doing 4 tens,1000 rms dvc 2ohm each pair on an amp@2ohms.Raise the back seat up, and you can get it to approx 13 in of clearance.All you need to get a pair of tens up under there

Thanks everybody for your input. While at church today, I came up with a brilliant idea (I have most of those at church) and I'm going to put a rear-fire box between my existing box and my front seat :D

You could probly get one good ten in a 1.0-1.4cu ft ported box that will more than likely sound better than the 3 subs you keep trying to put in there for the cause.It will only cost you some time, and maybe at the most for materials $20 to raise the back seat, and save yourself another sub/sub box, and time.You will get better results, and can utilize the subs you have by building a larger ported/sealed box/boxes for them, and get the potential use from them..IMO.Trust me..Raise that back seat to at the least 12 1/2 in, and youd be surprised what you can do.Seating will not change much for the passengers,if any at all.Save your money,utilize it.

Yeah. I bought 2 kicker cvr 12s and 2 memphis 10s today. I'm going to sell the memphis and my old quantum and put the 12s under my seat. My buddy has a box for some 12s of similar size and they fit under his and we have the same truck pretty much. So I solved the issue.

carpets absorb only high freq. at low freq carpet is pretty useless at absorbing sound. raising seat is easy and lets you fire forward. I'd get 2 great 8's run ported subs forward port side

I don't have the money to get anything else except to build a box. So I'm kind of SOL
