[QUOTE="bubbagumper6, post: 6876036, member: 567719"] No, your alt positive and battery positive are connected together in parallel, use whichever is more convenient (usually the battery terminal) The Big 3 is not a 100% fix for dimming, your electrical is not up to snuff, start looking into upgrading your battery bank & alternator. Start a new thread with that information if your still not sure. Your running a 3kw amp @ .5 ohm and you haven't done the big 3? What kind of electrical do you have backing that thing? Low voltage [I]will[/I] result in you blowing the amp. But to directly answer your question, 1 gauge is better than nothing, but not as good as 1/0. With the amount of power your running I wouldn't skimp on the wire size. If the batteries are connected in parallel it shouldn't matter which you connect to. There is some debate about whether or not you need to fuse the alt + to battery + wire. I generally advise that you do even though mine currently isn't.... [/QUOTE]
