Few Questions...
 

My roommate has a 96 Caravan, the aux. power (where you would plug in ur phone charger) does not work. Is it possible that he just blew a fuse or could the wiring be F'ed up. According to him one of his friends hooked up too much stuff to it.

Also he wants to upgrade his stereo equip. I believe there are 6x9s in the rear, how do you get at them? and the speakers in the dash, how do you get at those also?

Thanx for the help guys
