1/ Is putting an amp under the passenger seat a good location and 2/ what size speakers (diameter & depth) fit in the rear doors. I haven't removed the door panels yet but I've been told everything between 5in and 6.5in will fit.
i would think the only issue you would worry about is the amp heating up underneath the seat
