took the words out of my mouthIf the radio still functions, then it isn't a fuse issue. With a stereo problem like this, you'll need to go through the process of elimination like the tazmaster2007 implies. It's either a faulty speaker(s), or a loose cable connection somewhere in the stereo harness itself. You can make this job a lot easier if you have a multimeter though, just touch the wires that are plugged into the back of the stereo deck and find out which speaker isn't registering anything. This will enable you to locate the possible problem without having to take out all the speakers...best of luck.
