I have two 8" bazooka subs behind my seat firing into each other in an "Isobaric" setup (see pictures above). They set on the ledge behind the seat and the seat back conforms to them pretty well. I am a six foot heavy set guy and I can sit in my truck comfortably. The seat back will shape itself to the rounded tubes and dosn't seem to have problems staying at the angle that is proper for it. A sub box tends to take up a lot of room behind the seat, it if it is not built to fit against the cab back (pre-built boxes, for example). There is really NO ROOM under the seat for the subs, especially if you leave all of the seat springs and control wires under it. I have my amps mounted to the floor under my seat. (sub amp on driver's side and the four channel amp on the other side)
