Eclipse!!!!
Okay here is the situation. I have got a new system installed in my car. Actually just a new amp. 840watts RMS. I have a stock alternator and an about 6 month old Energizer battery. Got a cap installed, fine. The lights were dimming. 2 days later, the lights are dimming like mad. The HU is shutting off if i turn up the volume/bass. Im thinking its alternator. I am only getting 11.5 VOLTS to the amp when the car is on or off. Any one got any ideas if its the alternator or battery? It is having trouble turning over now. NO stereo until I get this fixed, which *****. Help me out guys, Thanks.
