Sounds like yet another common prob w/ the tours. My csvt is doing the same thing. I'll just be drivin down the road listening to a cd and you can hear the sound fade from speaker to speaker. I think it's done it a few times while I'm just listenin to the radio too. I'm glad I took my Pioneer out of my Neon, cuz the way it looks I'll probably need it soon. Hopefully you figure out what's wrong!!!!
