412 CVX Posted October 17, 2011 Report Share Posted October 17, 2011 the alternators will be powering the WHOLE car. not just the stereo. you should be JUST fine with 3 alternators as long as you have a decent battery bank.

My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

extremeauto Posted October 17, 2011 Report Share Posted October 17, 2011 Ok well im about to install a dd z2hv and its rated at 7700 watts at one ohm.so if you divide 7700 by 14.4 you get around 535 amps.if i put 3 pf dc powers 270 amp sp alternators on it will it cover it?they do 180 at normal temperature so that will be 540 amps but like on a hot day they only do 160 which that way will be 480 is that a huge difference to be worried about?i know i will be covered while driving but all these numbers are at idle.. you will need some battery's to take the strain of the alt but you want to have enough batt power to run the amp/amps you are running ....its gonna need all the power you can feed it Quote 1995 Honda passport 3.2 4x4 Frankenstein on a budget ballistics sound deader (roof only so far) kenwood mp3 usb audio control 3 (upgrading) hifonics mx-3 3 sets of massive px5 5.25s 3 sets of massive tweets phonix gold 5.25 componets x2 massive nx4 nano 200x4 mids sony xplod 600x4 watt high's 2 Fi bl fully loaded box walled @31ish hz 13.2 cube box/wall massive DB8000 Excessive amaperge 250 amp alt wir extrnl regulator daul runs of xs power xpflex 0 gauge big 3 raptor 0 gauge power/ground wire full run suriken 45 amp hour x3 shriken bt-120 batts,interstate 1100CA semi batt scytek galaxy 2way alarm still upgradeing!
