Sound like a bad alternator to me. What kind of car is it? How many amps is the alternator? How many amps is your amp pulling? If you give us some more info we will be better able to help you out.

Yep, sounds like a bad alternator or voltage regulator - or maybe even a badly slipping belt on the alternator. The stereo is not large enough to put a significant drain on the electrical system so something is broken.

Make sure that the terminals are tight on the battery (accu). To me it also sounds like a voltage regulator issue or a bad alternator.

Top Secret, I can tell you but then my wife will kill me.

wow u have to be a nub. Im going to try to be nice about this. You will need a capacitor to keep your head lights from dimming.

I'm sorry I have to disagree with AJRXtreme. If that car needs a cap for a 45x4 amp, WOW this must be something new on the market that i haven't seen before. I have to agree with everyone else, you should have an alternator or voltage regulator problem. Put a DMM on the battery and with the car running, check the voltage and then put on the AC then lights etc. and see if the voltage drops.
