Out of no where, the rear speakers on my vet stopped working and at the same moment they went dead, the clock reset on the kenwood head unit I have. The sub also stopped working which is fed by RCA cables from the head unit. The door speakers work just fine and I check the fade to make sure it didnt go nuts and move. I would think a fuse could be ruled out because the door speakers still work. Im using a RP5-GM11 adaptor for the head unit. Ideas?
