bassacadia307 Posted October 2, 2019 Report Share Posted October 2, 2019 I’m looking to construct my system around my available electrical instead of the other way around. My goal is to stay above 12.7 volts (this is a daily build). Please advise me as to what the max amplifier power is that I could look into using with the following: Singer 390A Alt (225A idle) Northstar Group 48 starting batt and two Northstar SMSAGM480 in the trunk (501 amp-hours total) 4 runs of 1/0 power/ground between all power sources (for a total of 8 runs) Thanks for your help!

slowfkncar Posted October 2, 2019 Report Share Posted October 2, 2019 Above 12.7 is mostly alternator, heavy pulses of current will be buffered by the batteries. 14.4 x 225 = 3240w 14.4 x 390 = 5615w Link to comment Share on other sites More sharing options...

What about simply above 12v then? Link to comment Share on other sites More sharing options...
