Infinity bass link will fit behind the back seat.
I just bought installed a Kicker 10" shadow Comp yesterday, it fits under the passenger side of the rear seat leaving me with the that load floor under the drivers rear seat, so still plenty of room. I can pull the box out or just sit it up right against the door if I need more space.
It's hits harder than I would have imagined it to! Love it!
