Power / Ground Cable Specifications

Wire Gauge
The measurement of the diameter of wire. As the gauge number increases the size of the wire decreases. As the wire gauge number decreases, the diameter of the wire increases. For example, an 8 gauge wire is going to be larger than a 16 gauge wire.

When purchasing wire, make sure that you know what size, or gauge of wire is needed.

Does what it should!

August 14, 2014

I purchased this big3 because I needed to upgrade to 1/0 alt wiring for the 320amp DC alt coming in. Kit has everything you need besides a fuse and block, nice flexible high quality ofc wiring and sturdy terminals. Even on the stock alt just adding this wiring increased my output and really helped stabilize my voltage. Something that just about any audio system can benefit from.

Big 3 done

August 10, 2014

Great wires, easy to install and gauge to spec, fits 0 gauge fittings perfectly. I also bought the NVX battery terminal connectors. Very happy with the quality of their products. Ended up with about 4FT extra wire.

Great for the Price

August 4, 2014

Thick 4700 strand. Not as thick as Knu but it is so much cheaper and it is well worth the money. Great product. Heat shrink is a little dinky and lugs have small holes so it wasn't easy to find grounds.

Good Wire, But That's It

July 5, 2014

Awesome, true to spec wire, fairly flexible being that it's such a big wire. The kit came with everything I needed to do the big 3. Now for the bad part. The upgrade did absolutely nothing for my charging system, the only thing I done was managed to blow money on something that I didn't need, made no difference. It's all a sales gimmick, the only way I think it will make a difference is if your running a really h/o alternator in which you would be required to run larger gauge wire or melt the smaller gauge factory wiring, catch stuff on fire etc, but for a stock alternator? Your just wasting your money. But I can't give this product a low star review, it's wiring. The wire is great, just the purpose of the wiring is a waste of time & money for stock alternators. Bad purchase for my app, or any similar app running stock alternators, don't recommend big 3's for it, just trust me and don't make the mistake I did..

Awesome kit

June 26, 2014

This kit has the same amazing high strand silver tinned copper that NVX uses in their amp kits. It is super flexible and easy to work with. The ring terminals that are included i noticed are made of copper with some kind of chrome coating, and they are very good quality. You will need some sort of crimping tool though. The only thing I didnt like is they suggest that you put a fuze within 12 feet of your battery on the battery wire but there isnt one included with this kit but otherwise it is awesome.
