I'd like to put one or two more (bigger) subs in my truck, but the truck is weird. The back of the backseat does not move, so behind the seat is not an option w/o unbolting the seat. Also, it's a 40/60 split backseat, and the tools and jack are under the small side, and this other sub is under the bigger side.

Any ideas? I wouldn't mind so much having them installed behind the backseat, but when I go to sell it eventually, I'll probably want to keep the speakers and amp, and I want easier access to it.
