ILikeEggs Posted April 6, 2014 Report Share Posted April 6, 2014 Going to run 2 dc 7.5ks soon, just wondering what kind of electrical I'd need for this kind of power? 1 370amp alt? 2? How many batteries? And how many runs of wires would be good? Link to comment Share on other sites More sharing options...
Amart88 Posted April 6, 2014 Report Share Posted April 6, 2014 If you have to ask.. I would say 370a alt as a minimum and at least 6-8 130ah batteries. My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
ILikeEggs Posted April 6, 2014 Author Report Share Posted April 6, 2014 So 2 370s and 6-8 batteries would be fine? Link to comment Share on other sites More sharing options...
Amart88 Posted April 6, 2014 Report Share Posted April 6, 2014 So 2 370s and 6-8 batteries would be fine? It should be ok. Hopefully you already have the big 3 done. You should have 6 or so runs of 1/0 ofc from front to back. And proper grounds. My 2005 s10 blazer build. 4 zcon 18's walled. Link to comment Share on other sites More sharing options...
ILikeEggs Posted April 6, 2014 Author Report Share Posted April 6, 2014 Where is usually the best place to ground? Would I want to ground each battery separate? Can i run the amp grounds to the battery ground, and then ground one battery and have the other batteries ground ran to that batteries -? Link to comment Share on other sites More sharing options...
