1995 Jeep Grand Cherokee Sound On 95 Limited S Radio Quit Indications That

The sound on my '95 Jeep Grand Cherokee Limited's radio has quit. All indications are that the radio head unit is still working, but no sound comes from the speakers. When first turning on the radio it will begin to play, but fade out within seconds. If the radio fuse is removed and put back in, the radio will play for 5 min then faded out.. The sound system is the stock Infinity One system that came in the Jeep.
