Ok, heres the real deal. Yes you can, although the above warnings are somewhat legit. Road noise is the biggest concern, as are crappy acoustics. I think most jeeps have 4 5x7 all around, but you can get a sound bar that holds two speakers and it mounts on the tubing overhead. I think they are removable. You can put a front firing 10 or 12 sub under the rear seat. It all depends how much you want to spend. Give me some numbers Ill give you some options and dont forget the "k".
