LOL!! Borrow one! Just curious, it may help to analyze the symptoms! You could also try plugging in an MP3 player into the AUX jack, but make sure the volume is not ALL the way up on the player, or you will overdrive the input into distortion. I'm trying to analyze if the problem is in the radio part, or the amplifier part.
As was suggested, reseating the connectors MAY or MAY NOT be the answer! The Push To Talk button for the CB could be stuck, all 4 speakers could be shot, (possibility but not likely all 4) the amplifier could be bad, etc. Have you tried with Headphones, and have you tried the intercom yet??
