100% OFC Wiring

Here at NVX, we want to make sure you are getting the most for your money. We pride ourselves on providing quality products, especially our power and ground wires. All of 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 power and ground wires are CTA-2015 compliant. 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.

Long-Lasting Design

Since our wires made with 100% OFC, we want to make sure that they last for a while and won’t corrode over time. That is why all our power/ground wires are silver-tinned, keeping them protected over time and not having to worry about them corroding.

Like all of our other wires, the power/ground wires are engineered with our EnvyFlex technology. The outer jacket makes installation an easy process since it allows you to route the wire even in the tightest spots of your vehicle.

Not Just for Your Car

Looking to add an amplifier to your marine vessel? Our power/ground wires are BC-5W2 marine compliant making them useful on boats and off-road vehicles. These wires are built to withstand whatever the weather has to throw at them.


Product Features:

  • Gray 4-Gauge Power/Ground Wire Cable
  • Premium power and ground wire provides optimal power transfer
  • EnvyFlex outer jacket makes installation and routing of the cable easy
  • Made from silver-tinned 100% virgin copper for a pure uninterrupted transfer of power and signal
  • Color: Gray
  • Length: 20 feet
  • Strand Count: 1813
  • BC-5W2 Compliant
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Good wire

I have this wire running my amplifiers in my truck. Very flexible and seems like good wire.

Good 4 Gauge

Good 4 gauge wire. True to the gauge and highly flexible. Made it really easy to wire up.

Nice cable.

Used this cable to power some amps. Very flexible and easy to work with. The good stuff at a great price point. I recommend using this cable.

This is the good stuff.

This review is going to sound similar to my review of the 14ga wire, but that's because they're both easily and obviously superior to the cheap stuff. I wasn't sure I wanted to spend this much money but without doubt, it's well worth it. This wire (and especially the 14ga speaker wire) is so much more flexible than you'd expect it to be, given the gauge. Impressive stuff. I'm a believer now, and will definitely buy this again when I do my own car next.

Great Wire

I had excellent use of this 4 Gauge wire and have heard promising things even before ive installed an aftermarket stereo. Overall a great product and I would recommend it to anybody.

Great product

For the price it was comparable to the more expensive kicker wire. Very heavy duty true 4 gauge would recommend for anyone looking to do a stereo or extra batteries

Great value.

Best wire for the price! True size and only the best in materials. Silver tinned ofc can't be beat for performance.

Look no further.

I was skeptical at first but after receiving the wire it's solid and I am satisfied.
