I need some help on what to do with my radio, with a 12 cd changer (1992 sc400). The problem was when u turned it own and put the volume on high, the radio just went off, can someone tell me what i should do? i tried to find the fuse on the radio itself and there is none, then looked for a fuse in the amplifier but there is none, does anyone know if there even is a fuse except under the steereing wheel because when i checked those fuses under the steering wheel they were fine.
