My stock toyota 3 in 1 radio will suddenly stop making sound when I'm cranking it up loud, no static, no warning, just Kaput. The CD continues to run, the tape keeps turning, the LCD stays on and so forth...it just goes silent. It won't do it when it's playing at low or medium loudness, just when it's loud. Does this happen to keep from blowing out the speakers or what's wrong with it? Anyone else have this problem? I asked the dealer about it and was told that it wasn't covered under the extended warranty, so I haven't been able to find out more.
