[QUOTE="sawinredneck, post: 415016, member: 9339"] Actually......... It would be possible, I belleve, and will hopefully be corrected if wrong, that electric motors once started only use 40% of the rated energy requirments. So to get it started would require 307.7 amps (4000w divided by 13v system voltage) not a lot to ask from a car battery now days. Then would require 184.6 amps until loaded hard then the amperage would rise acordingly. 200 amp alternators are not that uncommon anymore and the ingnorance I have seen (and been involved in) with car stereo systems it is not as unrealistic as it may seem, expensive yes, but doable! Kinda making me think about haw to power mine:dizzy: Andy [/QUOTE]
