Solved: stereo audio problem

I was having an intermittent audio problem, with one speaker cutting in and out. I thought the problem would turn out to be a flaky crimp connector on the speaker wires, and spent over an hour checking all of these connections to no avail. I finally decided that the stereo itself was bad and put everything back. Later, I took out the LCD TV to find its model number (to program my remote) and the audio began cutting in and out. A close look at the audio cables with RCA connectors (the ones with the four ears and center pin) revealed the problem: the RV manufacturer used the absolute cheapest cables possible. The ears easily bent under light pressure and weren't making good contact. Replacing these cables solved the problem. And I escaped the irritation and embarrassment of spending $200 on a new stereo only to find out that wasn't the problem.
