How to Find the Amps you Need!
AMPs = Watts / Volts x 1.25
Example: AMPS = 1000 Watts / 12 Volts x 1.25 = 104.1 AMPS (Round up to 110 or 120 Amp)

Most of the time you want 25% more than what is the actual requirement. If the AMPs aren't available as the exact Amperage, then round up to the next available.
