A week ago my radio stopped working as I was driving. No sound coming out of the speakers (other threads discuss a buzz when the amp is going). The radio has two fuses (9, and 44) and 44 was blown. Put in a new one, started the car and nothing happened. Checked the new fuse and it was blown. I've got the radio, a cd changer in the trunk and an amp somewhere. So I'm guessing I've got a short but I'm not really sure where to start. Just checking to see if this is a common problem and if there's a common cause before I dive into it. Thx!
