the sound in the radio just stopped working, it would come on for a brief period like ten min. and then it would go out again. i tried switching a radio and that didn't work either and i then checked the speakers and it wasn't that. The radio would come on but no sound then all of a sudden the sound would come on but it wasn't thru all the speakers at times it would be the front left speaker that worked then it would be the rear driver side then three speakers would come on, for the life of me I can't figure it out. I think its the radio and not the the speakers on Feb. 12, 2012 the radio worked for two days straight but still all the speakers won't function. any ideas anyone?
