So I recently bought the Pioneer DEH-4600 and installed it. Right after install, it sounded great, played great, everything worked. Went to go to the post office tonight and when i go to get in my car, my dash lights are on. so i turn my headlights on, then off and my dash lights go off. When I turn my headlights back on, the dash lights come on so I dont worry about it. Then I notice my stereo doesnt turn on. I get nothing from it, its dead. Obviously it's a problem with my wiring and being fairly new to car stereo installs (Ive installed 2, both with no problems), I am not really sure what could have caused this.
