I am running two amps one is 800w and the other is 300w. I have a cap on the bigger amp and it still really drains my battery at idle. I can see my headunit lights dim and my headlights dim when the bass hits. I was wondering if anyone knew the best way to redistribute power to my system and keep the alternator from blowing. I blew the alt. on my old car with the same system. Should I get a better battery? more caps?
