Need help with box for a 2004 Chevy sliverado extended

[Austin248]

Hey guys need some help with figuring out how I am going to get at least 1.5 cubic feet under the back seat of a Chevy sliverado 1500 extended cab. I am planing to get 2 DC audio XL 12 and they require at lease 1.5 of air, but I still have to be able to use the backseat. I already raised the seat 2in with a bracket that I made out of some square tubing

You will need 3 cubes (at least) after all displacements for the 2 12's not just 1.5. Go take mesurments of under your seats and multiply LxWxH then divide that by 1728 and it will give you the TOTAL(gross) cubes you have avaible.

Some things to look for.

If you do not have 14in of higth dont get 12's (IMO)

If you dont have about 4 cubes of gross of space may be more dont get 12's

If you cant fit them dont try to force them to work.

If you want to stay with the XL's try 10's if the 12's wont fit under the seat properly

Edit: if i am wrong by anything i just said guys PLEASE correct me. I dont want to give out false info.

Two twelves under the seat will be a bitch. It can be done but probably won't seat passengers comfortably. I would try tens and forward firing if possible.

Yeah, it's better to have midgets that can play than giants that are frozen.
