[QUOTE="ChaseinBass, post: 8393063, member: 655848"] So I ordered a triple alt bracket for my truck and am figuring out what I am going to need to run an 8k amp (crossfire probably) and my PPI 900.4 amp. And from what I am reading does this sound about right ?And I will be wiring at .5 on the subs. 900w + 8000w=9000 ish 9000/ 70% ? efficiency =12857 w/13v = 989 amps needed ? so 3x 270 alts =810 - 50 ish for the truck = 760 amps and 3x 110 ah batters = 330 760 +330 =1090 amps avail or will I really need another battery still ? does this look right ?
