people cutout holes in door panels for speakers, i dont like it, it messes up door panels, and they get in the way sometimes, you can cutout holes in the tops of those little tool boxes, on my car they took the liberty of cutting holes in the front of the boxes so they once had speakers facing the back of the seats, which i guess is ok. msa makes a great little panel for speakers that goes in the back, i was also looking at mounting a set on the headliner like a jeep. ive been stockpiling good speakers waiting to set it up, a four 6x9 speaker system with a nice cd unit, nothing special, but it will make music.
