Hi, today I was working on my subs then they played but after I placed my seat back my head unit does not turn on any more. If I insert a cd and press the eject the cd comes out but my clock and my head unit do not turn on. Is there something I could have pulled by accident because I had to yank out the rear seat belt but I checked the wiring and it seemed fine. Is it just a fuse? Or is my head unit dead?
