Answer 1

a new good battery wont solve ur problem, u need a new alternator like the guy above said

if ur system is above 1200 watts RMS you need a new alternator runing at a 100 amps recomended

Answer 2

YOu need a new alternator - not just a battery.

Most alternators put out just 70 amps (70 amp x 12 volt = 840 watt).  That 840 watt has to power EVERYTHING (headlights, fans, etc.)

So your alternator is woefully deficient.

Good Luck...

Answer 3

That's a lot of power.  You're going to need an H.O. (High Output) alternator.
