[QUOTE="KaeZoo, post: 461764, member: 554753"] Most of the time this problem is caused by a grounded speaker wire. One of the connections at the speaker terminal may have come loose and touched metal; or you might have put a screw through a speaker wire or pinched it against a metal edge. One grounded speaker wire will kill the sound to all the speakers. If you have a multimeter with a continuity function, put one test lead on chassis ground and probe each of your speaker wires with the other. (Disconnect the wires from the head unit first). If you find a wire with continuity to chassis ground, then that's the cause of the problem. Another thing you can try is to disconnect all the speakers from the head unit, then connect them one at a time. If the first speaker you connect doesn't work, try another. If it does work, hook the other speakers up one at a time until you find the one that shuts the sound off. If none of your speakers work individually with the head unit, then the head unit itself is probably bad. [/QUOTE]
