Need Help w/ Radio, No Sound

[Jaxonalden]

My radio didn't have any sound this afternoon when I got off from work. It worked fine on the ride to work but at 4pm, 95 degrees and the car in the sun all day, I got in and nothing. I did some checking and the clock was reading 11:00 (remember it was 4pm) the sound controls were all set to neutral. CD played and radio stations changed but no sound. It almost looks like the car had a power failure or power spike. Car started fine, top dropped and all other accessories worked.

I answered another thread where someone had the same problem blaming it on a thermal switch in the amp but the clock going out and settings has me wondering WTF?
