Love it

October 28, 2014

I ran this kit in a 2009 Aveo5 lt and it was very easy to work with and had plenty of wire to use. It made a major difference in the electrical system. I am running 2 Dc audio 12 inch level 4's and a hifonics 2400.1 d class amp and a hifonics 640.4 and not headlight dimming since I put this in the car.

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.

Awesome kit

March 24, 2015

The wire in this kit is top notch! The lugs and heat shrink made the install look professional. Wire also bends around corners very easily, I had read this in the reviews but I was surprised how easily it bends. Very happy with this kit. Five stars! Sonic was awesome as always

Great kit

January 11, 2015

This big three kit is awsome. I like how only one end of each wire has a terminal crimed on and not on both ends. Having the extra terminals to crimp on your own allows for a custom cut and crimp. I install car audio as a hobby for many of my friends and family. As well as their friends and relatives. I have used many kits, or custom made my own. This kit is extremely convenient and easy to use. It allows for custom cut and no need to purchase anything extra. Everything you could possibly need for a big three upgrade is in this kit. The wires are extremely flexible and will turn into tight corners. I like to hide as much wire as possible as I like a clean look. These wires were more than what I hoped and was looking for. I will most definitely be looking for spools of this wire for future audio installs.

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..

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.

good product

February 8, 2015

This item is good because you can get it all in one order. Its more expensive than ordering by the foot, the ordering terminals separate and all that. So it adds a bit of convenience. The cables are high quality. The terminal are also very good. Make sure you scrape, sand, or grind off the chrome finish . Its copper underneath.

Only thing that would make this kit better is if included a fuse holder and a fuse (like the competitor products) . The reason I chose this kit over the ones that include the fuse and holder, is this is OFC cabling. If your going to buy 0 gauge, no point buying crappy CCA.

Overall good value, would definitely buy it again in the future.

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.

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.

big 3 kit

February 18, 2015

this is a great kit. I bought off ebay a 8 ton crimper to crimp the lugs that needed to be crimped after you get them to length. This kit fit perfectly over my new mechman alternator lug. The big 3 kit now gives me all the power I need. The wires were plently long enuff and install was so easy. Buy it...it just works.

If i have the amp with the 35x4/5 A fuse , and 0 gauge cables , which comes with 300 A fuse, it's ok or not ? ( I have the sub NVX VCW 12" 850-1000 watt rms rated). Maybe I should use 4 gauge ? But I like 0 gauge..
Gelu P on Jan 5, 2015
Best Answer: Hello Gelu,

Bigger is always better, when talking Power/Ground and Big 3 Upgrade Kits. In fact, some enthusiasts will even run a DOUBLE strand of 0 gauge Power/Ground on a MODEST setup. So, we suggest sticking to the 0 Gauge if you can manage.
