Designed By Installers for You

Each amplifier wiring kit is specially designed and curated by professional installers. Each feature in the wiring kit was carefully chosen by these audio professionals. If anyone should know the challenges and headaches of installation kits, it would be them. Here at NVX, we look to them to actually design our kits, allowing us to bring these features to each one of our customers. We had a very high level of attention to detail when engineering these kits. Because of this expertise we were able to be amongst the first in the industry to include 8 gauge speaker wire in the box. This way everyone with high-power systems will no longer be forced to use 8 gauge power wire instead. It’s the details like this that separate us from the rest.

High-Quality 100% OFC Wiring for Any Application

Our amplifier wiring kits are top of the line compared to our competition. Our wires are made with 100% Oxygen-Free Copper with NO aluminum blend, unlike some of our competitors. Advantages to OFC include increased conductivity to carry more current to your amplifier, reduced strain on your vehicle’s electrical system, and improved heat absorption. Our wire is also silver tinned, which helps prevent the wires from corroding over time. NVX power and ground wire use EnvyFlex insulation which allows for greater flexibility making it much easier to work with. Our wires are BC-5W2 marine compliant making them useful on boats and off-road vehicles. At NVX, we are completely transparent with how many wire strands are in each cable, so you know exactly how thick each one is. Our competitors will never be that upfront with you.

More Wire Length for Wider Application

Other quality amplifier kits such as Rockford Fosgate or Stinger only give you 30 feet of speaker wire to work with. Here at NVX, we provide 40 feet in ours. In our 4-channel amplifier kits, we give customers 60 feet of speaker wire, two times as much as the competition. We also provide more power wire than our competitors as well with 20 ft of wire. That’s 2-3 feet more than other “premium” amp kits. With longer wire lengths, our amplifier kits make installations easier for larger vehicles such as SUVs.

RCA Cables Designed with You in Mind

Our audio interconnects RCA cables are constructed with twisted pair technology, which helps with outside noise reduction. The tactile grip RCA ends make for a tight connection for your amplifier. Our RCA cables are color-coded to help indicate left and right channels. We also offer shorter RCA cables for a cleaner installation. No need to try and hide unnecessary, extra wiring.

Amplifier Kit Features:

  • 1/0 Gauge Power Amplifier Installation Kit
  • Designed specifically for car audio systems over 1000 watts RMS
  • Made from silver-tinned 100% virgin copper for a pure uninterrupted transfer of power and signal

Awesome Wire

This wire kit is of the utmost quality. The wire is actually thicker than 0 gauge! I probably only needed 4 gauge wire for my setup, but this ensures maximum safety and power delivery without putting a strain on any of my components. Excellent item.

Great Wiring kit!!!

This kit has some of the best wire I have used. Its true 0 gauge and really flexible. The fuse block is really well made and easy to swap fuse. Over all I would recommends to other people.

good cable

The cable is thick and heavy! Decent product! What I actually bought was a "package" it came with a RCA cable as well. I was expecting a 300A fuse but got a 150A.

quality product

First thought upon opening this product was the quality the full spec wire is the only way to go really nice fuse block and the ends are already crimped on one end makes it easier to use i have used other products in the past that cost way more money and i dont think they are as nice as nvx its the only way i will go for now on !!!!!!!!!

High Quality Kit

Top of the line amplifier wiring kit. No cutting corners on materials here. Heavy gauge, quality wire. I have it installed with the NVX JAD 1200.1 amplifier and it is the perfect set-up. The only complaint I have is that it doesn't come with RCAs. High quality, true 0 gauge wiring that keeps everything running efficiently and cool!

Amazing Amp kit

The wire in this kit is incredable. It is copper wire with a silver coating around it. It is the most flexible wire of this size that I have ever seen! I even love the 12 gauge wire that comes for the speakers. This is the best kit I have ever purchased hands down. The cons though are it doesnt come with RCA cables, This did not matter to me as I did not need any anyway.

Very Good Product

Ive used numerous high end kits in the past and this kit is just as good as any of them, if not better, at a fraction of the cost. The amount of wire is great especially considering what some companies call 0 gauge, this is true 0 gauge. Add to that the fact that its silver tinned and that makes it an incredible product. Its flexibility is also note worthy, especially as most other brands of 0 gauge is fairly stiff. This is a great product.

Great true 0 guage

This wiring kit is awesome I put it in a nissan sentra and it is super flexible to make tight bends. Really all around great quality I liked that it came with ring terminals pre crimped onto the kit. This is my first nvx wiring kit and I won't use any other brand now.

NVX Xapk0

It is a good product but not worth the price I kinda wished I bought
Something cheaper that's same quality and comes with more
It didn't come with RCA wire I had to go pay 30$
On top of the 160$ just spent for the kit I think there stuff
Looks cool and does the job but not worth the price

Heavy duty wiring

I bought this to help with my system shorting out and it worked awesome!! I had my first system installed and they used 4 gauge it it didn't work out to well I ordered this nvx product and ran it all myself and it is fantastic I have not had a problem with my system since then! I'm running an nvx vcw 152 and a kenwood 2000 watt amp it hits hard and sounds great thanks to sonic for having this at a greT price and fast delivery
