125 amps * 14.4 volts = 1800 wattshow many watts per amps is good is there a formula im missing. got a 125 amp alt whats most watts you would wanna run off it ?
also depends on the battery and how efficient the amp is....i run 2k on just a single batt and 120 amp altIt depends on how much your car uses. Do you have power windows, A/C, navigation, etc? Many factors make a difference including efficiency of the amp. A/B amps will be far less efficient
