Audio system has lost power

Does anyone know what would cause the stereo/CD Changer/Power antenna to suddenly have no power? I thought it was the fuse but the clock is also on that fuse and it is working. Is there a harness or something that powers just these things that could have come loose?

no radio power

you have 3 power supplies to the radio. one is from the headlight switch, one for memory {fuse in engine compartment, 5 amp}, and the last one is the ignition { fuse under dash}. hope this helps

And that's assuming no one changed anything in the car. Expect to find that there is an inline fuse somewhere.
