i have 3 10's, 1800 wat amp, and 2 10" neon bars connected to the amp, and the amps power wire to the battery is 4 gauge. then i have a fuse box on the power wire that uses the big 80a fuse.
What i need to know is what to do to keep battery alive, use the remote starter after i leave it or something? its a 1990 accord stock alternator. does this stuff draw power when the car is off?
