In such case.. a 220a should do? i need to get a volt meter to double check. So with my formula.. 110-60= 50a - 65 (averaging 650rms as to not blow the L7). = (-15a) which an extra batt. should take care of. right? I do your method ..soon as i grab a meter.

got it. Alternator's amps (110) - subtract 60a for car accessories. subtract audio amplifier's draw = 10:1 ratio -watts/amps compensate the negative balance with battery(s). thanks for the info and prompt response. love this forum already

really? is that because of the 650 rms I'll be limited to ... or because the efficiency of the Class D? or what?
