snafu Posted June 7, 2012 Report Share Posted June 7, 2012 Math. 3,875 / 75% amplifier efficiency = 5,166.67 Watts Input 5,166.67 Watts / 14.4 Volts DC = 358.8 Amps Required to reproduce sine waves at full output 358.8 x 50% = 179.4 Amps Required to reproduce music at clipping If you'll be listening to music with this amp, then . . . Alternator size = 179.4 Amps + Stock Requirements + 10 Amps for each additional battery (3 Amps for each XS Power Battery) + 20% buffer Otherwise, use the BIG number . . .

hertz2beloud Posted June 7, 2012 Report Share Posted June 7, 2012 (edited) Going by birth sheets and the formula you posted my 220 amp alt is not enough for my car. I wanna scream right now. I guessed the effiency of my rf amps at 60% because I did not know for sure on them Edited June 7, 2012 by hertz2beloud Quote Link to comment Share on other sites More sharing options...
