Amp gain
No problem. People said I couldn't fit 12's behind my seat but with a little bit of manipulating They fit just fine. I would pull the back panel out and see what kind of space if any that is there. There are alot of shallow subs that don't require alot of air space that may work if you are willing to get your hands dirty. I would check the passengers side. ya never know till you see for yourself. There was 5.75 inches behind mine that supposedly didn't exist on mine.
I think Alex is right on this one. The 06s have little to no room behind the back seat. I fit my amp back there and I feel that is pushing it. Maybe if u cut the liner out and removed foam from the seats, but I would say not. And the seats until u figure out how they come out are a pita. My amp hasn't overheated yet, so hopefully it won't with such little air space. I think one ten under the rear seat, on the drivers side, opposite the jack would be best.
