I am looking to put an 8" sub into my Porsche boxster. The only place inside the car is behind the passenger seat. I would say I can only get about 1 cuft of box in there. Can anyone suggest an 8" sub? I have been looking at the ss rl-i's and some jl 8" subs. I just want one that will give pretty good sq and get kind of low. Thanks in advance. Its a mid engine with a trunk in the front and a trunk in the back, but I don't think I would be able to do much more than feel the subs if I put them in either trunks.
