Put the radio someplace where the heat won't mess it up....mounting on a sub box is also a bad idea, the "boom-boom" can rattle things loose and cause cold-solder joints. If you need your radio worked on but don't know any local shops that know what they're talking about, try RAR (Radioactive Radio) or Sparky's CB shack...both of which are online. The have a mail-order repair service and both are excellent places along with GI Joe's. Need to have patience though....it'll be a few weeks. It's always better to have a reputable shop do the work rather than some hack.
