dirtboi22 Posted October 19, 2009 Report Share Posted October 19, 2009 ok, what would i need to run 4k rms? like alt wise and power wire? and i think i want a high idle output alt. so i dont know what the highest amperage those can put out are and if i would need an aftermarket batt.

dirtboi22 Posted October 19, 2009 Author Report Share Posted October 19, 2009 i would like to stay away from extra batts if i could, i would like to run a stock batt with the necessary alt if possible? but im not sure if i will be able to do that. just wondering, to figure out what i need do i just add all the ampers from like all my car functions, with my head unit, and amplifiers?

P4killer_ Posted October 19, 2009 Report Share Posted October 19, 2009 (edited) if you get an absolutely monster alt then you could prolly keep it down to one extra battery so a 300amp alt + a kinteik 2400 if you really are looking for 4k rms and we'll say the amp is 80% efficient your electrical will need to be able to support 5000 watts (5000 * .80 = 4000) please correct me if im wrong so 300amp @ 13v = 3900 watts a 2400 is 123ah so 123 * 13 = 1600 so with that you could support 5500 watts total minus some because of course your car needs some of that power to run etc and this doesnt figure in any mid/highs, just the 4k for your subs this is just a rough outline, and again correct me if im wrong. also there is plenty of videos under the hifonics section with mike styers doing some tuts about stuff like this. hope this helps P4killer.

barros57 Posted October 19, 2009 Report Share Posted October 19, 2009 1/0 power, and depending on your car, I might suggest keeping your stock alt and adding a second alt where your ac pump or something used to be. A second battery would be a good idea Quote My 93 chevy truck Orion HCCA 15's Build 6K HID's 2 orion HCCA 15.4 2 AP30001D's 2 optima yellowtops, 2 C&D 270fr's, all 3 tsunami 1/0, CS144 190 amp Rockford p200-2 Rockford p200-2 Rockford p300-1 Kole KX1 5500D -broken Link to comment Share on other sites More sharing options...

mr.p Posted October 19, 2009 Report Share Posted October 19, 2009 did either factor in the amplifier efficiency? Quote DCAUDIO BALLS DEEP Link to comment Share on other sites More sharing options...
Boon Posted October 19, 2009 Report Share Posted October 19, 2009 I ran 4kw off a stock alt and 1 G34 yellowtop... not sure I would recommend it though Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
Boon Posted October 19, 2009 Report Share Posted October 19, 2009 did either factor in the amplifier efficiency? Why are they both multiplying the reserve capacity of the battery :S Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...
