[QUOTE="n8skow, post: 7575042, member: 610656"] My initial guesstimate was actually a bit too high after doing the math, but where are you getting 10 amps from every 100 watts of power?? V (voltage) x I (current in Amps) = P (Power in Watts) So with the engine running, we'll say 14.4 volts of input power, and we're limited to 80 amps of current (continuous). 14.4 x 80 = 1152. This however assumes 100% efficiency, which is impossible. Boss doesn't list the efficiency of the amp, so I'm just assuming the typical Class D efficiency of 80% So take 1152 x .8 = 921.6 watts [/QUOTE]
