jpac Posted May 12, 2010 Report Share Posted May 12, 2010 My amp wont stay on. When it does the lights will dim. I think that its making the battery go low. Because if you let it charge for a while it will run ok. Im looking into a hi-po alt for my car. Does any of the vendors on here make an alternator my m30? -jason Quote Link to comment Share on other sites More sharing options...
Guest Posted May 12, 2010 Report Share Posted May 12, 2010 you dont need a new alternator for a "lame-ass 800watt amp". check for loose grounds and power connections. use a DMM and check the voltage of the battery when the amp is turning off and doing other stuff.
