[QUOTE="n2audio, post: 5492571, member: 540940"] People go WAAAAAY overboard with the whole "big 3" thing. The whole concept that you need garden hose size charging wires when you're only running a couple K (or a lot less in this case) is completely unjustified. In a situation where you have a car that happens to have undersized wiring and you're adding a big alt, of course some larger wires are a good idea, but in this case there's no way the 2 ga is the issue. It's more than enough for 2 or 3k imo - with 1/0 from batt to amps. 2 ga at a length of 5' will drop 0.2v at 260A. What is not acceptable about that?? And that doesn't even consider what stock wiring is already there, OR the fact that the alt will rarely, if ever, actually be producing that much current, especially playing music. If you were to go with 0 ga voltage loss would fall all the way to .13v for a grand total of 0.07v difference. Even at 00 it's a 0.1v difference, or essentially, no difference at all. Math is your friend, use it. no Uhh, not sure where you're getting your data from, but 15' of 2 ga can deliver over 200A w/o dropping more than 1/2v at 14v. I have NO idea where you're getting those numbers. I would be interested to see it though. [/QUOTE]
