ok, I have a problem, my cars battery keeps dieing, and I know why, I am running 1200watts out of my battery for my amp, and that equals to 100 amps, and that is way more then my alternator can't put out. I thought about adding another battery, but that would make no sense, it would still use the same amount of power from the two batteries as of one, it doesn't matter if i have 10 batteries, my alt. still has to charge them. so it will give me no more power. and as far as a cap goes, the cap would just give the subs straight power, but that does nothing good for my problem, I'm not trying to improve S.Q, I just dont want my battery to keepon dieing, what can I do,,,,, am i correct?
