This is how it happened. it was working. but my friend had a problem with his deck. he installed his amp. he then turned on his deck and it was working. he pressed eject and no cd came out, but there was a cd in there. after that his deck wouldnt turn on. so i hooked my perfectly good running deck to his car. and it wouldnt turn on also. so i hooked my deck up back to my car and it still wont work. please help me. IS THERE A FUSE IN THE DECK ???
