Thread: no sound!

well im giving up for the night i have been working on this for hr's now with no progress. hears the run down i have checked and re checked the wiring and it is fine. the deck turns on and the subs play but nothing will play over the factory speakers. what on earth could cause this? the other odd thing is how the other cd player had worked fine for yrs and just so happen to take a crap 2 days after i get it.i also hooked it up out side of the car just to power and ground and it still had the same problem where it turns on then off.i was planing on taking the gp on a 5hr trip wednesday but with no radio might have to take the jeep. also he one the is hooked up now is not the one that took the crap it is a newer working one out of my jeep.
