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:

  • 8-Gauge EnvyFlex Power/Ground Wire Cable
  • 20 ft. spool for medium-sized projects
  • Strand count: 735
  • Metallic powder blue jacket insulates and protects against damage from extreme conditions
  • Flexible multi-strand cable bends and twists to meet your installation needs
  • Ideal for systems between 200-400 watts
  • True to gauge for reliable power handling and secure fit
  • Transfers audio signal with clarity and minimal distortion
  • Made from silver-tinned 100% virgin copper
  • BC-5W2 Compliant
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Great Wire!

Great Product, Price, and Quality.
I love NVX brand for both the quality, and low prices of their products.
Just Google NVX wire thickness compared to other brands, and the pictures will tell the truth.
I bought this cabling to run a fuse block for accessories, and bought other NVX amp kits for amps, and an inverter.
Perfect for my needs.
I can highly recommend NVX wire, as well as many of their other products.
