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 16 gauge speaker wire in the box. 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.

  • 4 Gauge Power Amplifier Installation Kit

Great Amp Kit

I have been buying and installing car audio for about 18 years and out of all those years I have to come across an amp kit like this. This is the best kit I have ever installed. The wire is true to gauge ofc. I installed it in my car without any problems. Very flexible easy to work with. If you want a good amp kit don't buy this one but if you want a great amp kit purchase this one.

Quality Kit

I bought this kit because it is high quality, uses true 4 gauge wire, and comes with 20ft. of power wire. It is working very well with my JAD1200.1 amp. I get about 0.5V of voltage drop at full power, 1 ohm impedance on test tones. I am very happy with the performance of this wire.

Super Product

Very nice product. The quality of the power and ground 4 gauge wire was great. Already had one end prepped with a terminal and the power wire has a protective sleeve for about 4 feet. The only complaint I have is that the plastic cover that goes over the fuse holder doesn't snap very tight, easy to knock off and expose the fuse. I put electrical tape down both sides to help hold it on.

Great Product

This sound deadener is great the best I have ever used. It is very thick and sticks to anything. I used it on my rear speaker deck cover. I didn't know if it would stick do to the that the cover was made of fiberglass. It worked, stuck to the cover like glue. The only down side to the product is like any the black tar like substance if you get it on your hands or fingers have to use paint thinner to remove, other than that the product sticks to just about anything. The price is great too, dynamat for the same about cost about 3 times as much. The NVX is a much superior product than dynamat also not paying to fill chip foose back pocket.

I'm addicted to NVX!

I used this in my 2008 Town & Country too! I purchased this kit to power my NVX JAD900.5 and could not be more pleased! Good quality, thick, durable, flexible... the list goes on! This made my install so easy! I can find only one problem... I don't have enough vehicles to do installs!! I can't get enough of NVX! I would be happy installing NVX on a daily basis! Everything NVX is fun and easy to use!! Thanks guys... you ROCK!

Great product

The kit is great true 4 gauge power and ground wire. The pre installed ring connectors makes it so much faster and easier to install. Handles the power of my two amps well no overheating or anything. Great product and price.

I will never buy another brand. NVX is the real deal and affordable also. I would recommend anyone to NVX and SONIC ELECTRONIX.

Great buy

First time buying NVX product, very good overall quality. The wire itself was very flexible and seemed to be true to the gauge listed. It had more than enough to hook up everything I needed. I actually had extra parts. Keep in mind, this particular kit does not include RCA's, I did not need them for my install as I already had some. The only thing I had an issue with was the top of the fuse holder for the fuse box seems to fit a little loosely once the fuse box was bolted in. It has not come off as of yet, but I've only had it installed for a few days. Overall, compared to some of the other big name brands, I can't see why you'd pay more for their product when this one is very high quality at a great price. Thanks Sonic!
