1point21gigawatts Posted September 3, 2020 Report Share Posted September 3, 2020 That would be sufficient if you had that d3100 as a secondary battery and another agm under the hood with a big 3 upgrade. And you won’t be pulling 415 amps of current. No where near. Those current readings are readings done at the lowest impedance stable and on a sinusoidal signal, not music. Music current draw is around half that value. Then you have to factor in impedance rise which minimizes the current draw as well. There are fluctuations in impedance rise and in music that there would be at times quick bigger current draws. Then you have to factor in the current the alternator does at idle and at certain rpm’s. And xs makes an agm battery that would fit in your vehicle factory battery slot. That and a big 3 upgrade would work just fine. What brand of alternator are you using?
