Well, i barely put a new battery on my car about 2 months ago. my car has really, really bad amps on the guage when i turn the lights on in the night. The more things i turn on (heater, high beams, blinkers)the lower the needle will drop. last time i checked the alternator was good. ive thought about changing the alternator to another one that makes more power. i also have a 300 watt amp powering a 12'' woofer. how many amps should i buy the new alternator? Could this be my problem??
