you could do a couple 10s or shallow 12's tw5s if you have the cash. id get about 1 cubic foot per sub you can build a box like on of my buddies did that fits snug under the seat raised off the floor about 1/2 in and build it with the same length and width as the seat. and make it as high as you possibly can since youre majorly crammed for space.

i orginally had 3 subs in mind the jl8w7/jl 10w6/dc sounds lvl3 10'' and all those where about 500-600 watts each but then i remember the fi q's in 10'' sizes are 0.2-0.6cu.ft for each and can take 1000 watts..so i think im going to go with 2 10'' fi q's..what do you guys

look up boxes on ebay or somethin like that, they probably already got boxes designed to go under the seat of ya truck for 10's or 12's or whatever ya want.

well there box will only accept a magnet no bigger then 6.5'' and the q is 7.5'' but its ok my biggest problem was finding a sub that will fit under the back seat..2 of them actually and still have some balls to it and lucky i remember the fi q..i will just have a box built to fit these subs and pretty much call it a day..lol
