I now this has been addressed on the board previously, but my searches aren't finding relevant threads.

How do I remove the stock radio on a '90 245. My two rear and front left speakers don't work, and I suspect that there is a bad connection at the rear of the radio. All four speakers are wired correctly, and when I tap on the radio face, the left front speaker begins to work for a few minutes. It's either a bad connection or the volume/fader/balance pot is bad. Either way, I have to remove the radio to inspect and/or replace it. Thanks a bunch!
