SO i have a 2000 Cadillac Catera with the Bose factory sound system in it. It seems that if i listen to it with the volume about 3/4 of the way up it just randomly shuts off. I have not been able to pinpoint the reason. It does this when im listening to the radio or a CD. Ive heard that there is some sort of chip in the amp which overheats, and i need to take it off and re apply with some glue stuff.

If anyone has any info or could point me in the right direction it would be greatly appreciated,

d/c the battery
reconnect
see if continues

well the batery has been disconnected several times already so i dont think thats it. i think it has something to do with that chip in the amp overheating. i heard that the adhesive they use to keep the chip in the amp from the factory is no good, so i should take it off, clean it off, and reapply it with new heat adhesive stuff. Makes sense cuz the stereo only shuts off after i listen to it for a little while with the volume at 50% or more.

Hay man im having kinda the same problem with my 2002 sts but it never happened until i changed out the factory head unit. is your head unit factory or aftermarket. mine goes out randomly at different vol. levels at least once every 15-20 min. im thinking its the GMOS-06

factory everything as far as the sound system goes. I still havent gotten around to messin with it though to try and see whats wrong.

Hi, I'm new to this forum. Did any one find out what should be replaced when the radio shuts off? I've notice that if the radio doesn't work, the trunk nor fuel cap release buttons work. Any suggestions on how to repair this on a 2000 Catera?

Could possibly be throwing a fuse or breaker type thing when it gets to hot? Does it work again once you turn the car off then back on?

we already determined that it was the multifunction module. See this thread for a little more info and a couple other links.
