upgrading my 2000 v6 mustang alternator next week. I'm pushing around 3000 watts and my lights atart dimming about 15 minutes after music play. my thought is the alt cant keep up with the power leaving the battery so my question is, my stock alt is 105 amp but I see them online ranging from 160 to 250 amps. should I get the biggest I can afford or could too big do damage something somehow
