P4killer_ Posted November 13, 2009 Report Share Posted November 13, 2009 Those are just guidelines really and your calculation is right if you feed the amp 3k you'll get 2400 or w.e you said output approximately. But really I mean if you have a 3k amp you could use one k2400, d 2700, or 3100 and you would be okay. Two of those batts. Would be ideal imo. But you could make it by with just one depending on your voltage.

zerosktr111 Posted November 15, 2009 Report Share Posted November 15, 2009 Yea I just watched both vids. So I would say the 134 ah would be the best to go.That would give me 1742w at 13v. My alt is 140 stock. So subtract 40% from that would give me 84 amps with my alt left. So then do I multiply 84 amps by 13v? to get my alt output? If so, that would give me 1092. so 1742 + 1092=2834 If my amp is 80% efficient then it would be 3000 x .8=2400 right? So theoretically would I be good? Let me know if I did something wrong, thanks Sorry man... I think you divide 3000 by .8 so it would be 3750 watts.

P4killer_ Posted November 18, 2009 Report Share Posted November 18, 2009 yea thats if your looking for how much wattage input is needed to make 3k ouput.. his calculation is still right however, if you supply the amp 3k @ .8 effeincy youll get 2400 output..
