audio/electical experts HELP!
i recently put a stereo sytem in my car (1988 SE) consisting of 2 12" subs and a 600 watt amp. whenever i turn the head unit up very loud, it shuts off (the head unit) and then comes on a second later. it will keep shutting off until i turn the volume down. i have noticed that i do not have to turn the volume up much at all if i have the headlights and/or the windshield wipers on. i am thinking that there might possible be some sort of circuit breaker or resettable fuse that limits the amount of power coming out of the alternater. has anyone else had or heard of this problem?? please reply with any suggestion.
THANX!!!!

I used to work with car stereos at Circuit City.
I would suggest the following remedies.
1. Check to make sure that your amplifier and deck have a good, clean ground. They shouldn't be grounded to anywhere that there is paint. If there is paint, scrape it away with a screwdriver, and then reground it.
2. Check to make sure that none of the speaker wires on the amp is touching another speaker wire.
3. If you are running the deck to stock speakers, check to make sure that none of the stock speakers wires are touching each other, and check their ohm load. You can do that with a multimeter.
4. Check to make sure that none of the speaker wires is touching and kind of ground.
It sounds to me like your deck is doing what's called "clipping." It loses power when it gets turned up, it's usually because one of the speakers is blown, or the speaker wires are touching each other, or some other ground.

Could it be the internal amp is pushing his other speakers so hard its safety circuitry is cutting itself off. I had an amp short my sub in my old car out all the time in the summer due to poor circulation. What kind of deck is it? RMA per channel. You don't have more than 1 speaker per channel hooked up do you? No series wired tweeters?
