Re: no audio

Try to be more specific, but I will say that if one of your speakers is grounded out and/or blown, it will shut off the internal audio of that deck for all 4 speakers. Try disconnecting speakers one by one and turning the car on and off until you figure out which one it is. Also, what year/make/model car is it? Does it have bose? you may need to power up an additional wire to get it to play. Let me know, be as specific as possible.
