Anything bigger than stock wiring is better. Most use 1/0

Yes it is regular copper wire

It all depends on how many amps you plan on running.. If you're running extreme amperage you need the right size wire or else you're not getting what you should out of your current flow

plus the price difference when doing big 3 4 gauge vs 1/0 is close to nothing, why not spend an extra few bucks and upgrade such a small amount of wire if you ever decide to upgrade.

^ this

Why not just leave room for upgrade later? Regardless of run length, 4 gauge can only carry so big of a current. Might as well just do 1/0.

im not running anything to extreme since this is my dd just a cheap 1400 watt but thinking of adding another and this one already dims my lights when i have it loud which is almost always lol didnt get time to work on it today got called in to my second job on my day off sux thinkin 2 jobs and a hobby dont mix one of them is about to go and its not gonna be the hobby

It kind of depends on how big of an alternator you have. 4 gauge wire can handle the output of any stock alternator I've seen, but as mentioned before, many ppl just upgrade with 1/0, so there is no need to redo it down the road if you upgrade.

Its just the stock alt on an 01 maxima will probably put a bigger one on it when this one goes out so yea im just gonna do 1/0 the first time screw doing it twice that cost more than just doing it right the first time my time is expensive lol....work smarter not harder

Exactly. My stock alternator is 130 amps.. I think 1/0 is good for 250 amps under 25ft (correct me if im wrong)

I also think I paid 25-30$ for enough welding quality wire 1/0 to do my big 3 lol so no big loss there.

Just do 1/0.. its cheap for a small amount, and you can upgrade (doubt you will ever go above 250 amp alternator, I know I wont)

I believe Knu's CCA 1/0 is good for 250 amp and their OFC stuff is rated at 350 amps, So if you get the CCA you'll save some money and it will be able to handle plenty of current.
