is it an aftermarket head unit? If so, there is a common problem with the aftermarket radio harness fitting into the stock one. I had the same problem before after I installed a new head unit. Your best bet would be to take out the deck and play with the harness and make sure the speaker harness is clicking when you connect them. What is happening is the harness is coming loose therefore the pins are not touching which means the speakers arent working..
