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!!!!

 

How many times did you post this same question?

See your other post for answer/clarification

 

Damn man i have the same problem, but it doesn't happen all the time. I notice that if got it up loud the deck will flicker when ever there is deep base, and sometimes it just completely cuts out. very annoying, and haven't found the problem or a cure yet
My guess is its just not getting enough power, it read only 4v on the meter...

 

BigMike you need a capacitor on your system... 1 farad per 500 watts is about right.
