AMI CUSTOMS Posted June 8, 2012 Report Posted June 8, 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 . . . Methinks it's time to make a calculator and stick it on my web site . . . Good idea I am gonna make an excel sheet that does this.

SnowDrifter Posted June 8, 2012 Report Posted June 8, 2012 (edited) look at my signature. I drop down to maybe 13 volts at full tilt. That's weird. I never went below 13.4 at the inputs on the amp on my stock alternator. I only had 4 of the ram_designs batteries and 1 run of 0 gauge to the back. Edit: and that's at a half ohm too Edited June 8, 2012 by SnowDrifter Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
