I'm hoping that someone can help me with my radio problem... I have a 91 SHO with the premium sound system, and my AM/FM radio stopped working. The cassete player works, the separate CD player works but the radio went dead, not even finding FM stations anymore. First I thought it could be the antenna, but I replaced it and it still wouldn't work. I ended up buying an used stock radio coming from a 93 SHO (w/ premium sound) but when I installed it there was no sound coming from any of the players, but the radio is now finding the stations (the antenna is fine). I'm thinking that the 93 radio might be incompatible with the 91 amplifier... is there a way to bypass the amplifier and hook up the speakers directly to the radio? Any help will be appreciated.
