Max recommended wattage for my electrical?

[bassacadia307]

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!

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

Thanks. What about simply above 12v then?
