Is it possible to raise the rear seat in my 2003 dodge 1500 quad cab? I just glanced back there before coming to work and it looks like it is just bolted down with 4 bolts. If it is possible, this would really help with the air space needed for subs.

 

If its like my '06 then no. There are hooks in the back of the cab that hold the back of seat, raising it would bring the seat off of these hooks.
