you could do it, but it'd be touching the back part of the seats most likely. when i removed my rear seats in my AC, there's a slight recession along the back of the bench. i'm sure an amp could fit there, but i wouldn't do it due to lack of air circulation back there......but there's these two vents in the rear of the cabin behind the bench, so maybe you can get something to work. i just opted to install my amps under my front seats.
