I have a AVH-P4100DVD and just the other day i get in my car to go home and there is no sound coming from my speakers but my sub is still working. I pulled the radio out and checked all the wires and noting was disconnected everything seemed fine i plugged it back up and cut the radio on and the speakers was working but then it stopped again after about 10 secs. I figure it might have to do with the wiring in the car so i got a speaker i had laying around hooked it up speakers wires coming straight out of the radio and it didn't work either. Is there anybody else that has had this problem with the P4100 or is my radio fried on the inside, I haven't even had it a year. Thank you for any help!!
