Karkov Posted February 5, 2014 Report Share Posted February 5, 2014 I'd add a second pos and double up the neg to where you have it now. You might not need it but It definitely couldn't hurt. I agree you don't need to run a neg from the front though. Okay, so I have a mechman "260" amp alt, 850 cca agm batt up front, big 3 done, and 2 92 ah cell tower back up batterys in back. Would it be more beneficial for me to add a 2nd run of positive from alt to rear batts, or do a run of negative from the negative of front batt to rear batt negative ? Oh sub amp is dc 2k and I only drop to like 12.5-12.6 at idle wangin away at full tilt on a dc lvl5 18. I certainly would not run a second run off the alternator. The stud IS NOT a good distribution point to run to the back of the vehicle. That will cause the regulator to overheat and become LESS efficient. I would run a larger cable to the front battery and then distribute from there. The ground is totally up to you if you want or feel the need to run it. otherwise I would make certain it is clean and tight So I have a question then, that applies to this thread, right now I have 2 runs of 1/0 OFC coming off my alt to my under hood battery. Yes it goes to the under hood battery but it is two runs. Would it be better to make it a single run of SCHA 2/0 OFC instead? Would it not matter at all? I have multiple batteries under hood and in the back and plan on running some big power (have 7 amps in my spare room that need to go in).

ToNasty Posted February 5, 2014 Report Share Posted February 5, 2014 It wouldn't matter since you already have it. Plus a single run of 2/0 ofc can handle more current then 2 1/0 ofc. Atleast that's my understanding. ***Super Sellers List***http://www.stevemeadedesigns.com/board/topic/25829-super-sellers-buyers Link to comment Share on other sites More sharing options...
alaskanzx5 Posted February 5, 2014 Report Share Posted February 5, 2014 IMO if the alt can't produce more power then a single 0 gauge wire can handle then the 2nd run is kinda pointless. t1500bdcp 2 t2d4 15" 1 t600.4 1 t400.2 1 set p1 tweets singer alt, tons of wiring, smd vm-1, 80prs, back seat delete, still in the works, aiming for a 145-147 with the ability to play 25hz up to 50hz.

Karkov Posted February 5, 2014 Report Share Posted February 5, 2014 IMO if the alt can't produce more power then a single 0 gauge write can handle then the 2nd run is kinda pointless. I hear ya. BUT most people over do their electrical anyways. Also, it's the Mechman 370 Elite 6 phase (252 at idle) so I wanted to make sure I didn't restrict it in any way. From alt to batt. is cheap short run, all good.
