I am looking for info on a sub box for behind the bench seat on my 93 Reg cab Chevy PU. I am pretty tall and require the seat to be in its full back position, thus I have very little room for anything back there. I am only intrested in one drivers side box (so I can retain factory jack location) with the largest diameter speaker I can fit in there. The only one I have found so far is a Q logic box at the tune of $250...for just the enclosure. This is not going to be a competition system I just want something that sounds pretty good.
