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:

  • XW4BL5 Metallic Powder Blue 4-Gauge Power/Ground Wire Cable
  • Made from silver-tinned 100% virgin copper for a pure uninterrupted transfer of power and signal
  • Premium power and ground wire provides optimal power transfer
  • EnvyFlex outer jacket makes installation and routing of the cable easy
  • Color: Metallic Blue
  • Length: 5 feet
  • Strand Count: 1862
  • BC-5W2 Compliant
  • Authorized Internet Dealer
  • 1-year Manufacturer's Warranty

Good cable for the money!

Very flexible for tight routing applications. I only bought 5 ft to use for a ground, but I like the wire. No complaints here.

Best wire yet

This power wire is not stiff like most of the others and easy to bend where you want it

NVX Wiring

I am satisfied with all of NVX Audio's wiring.. It has the nicest appearance of wiring I've seen.. It is comparable to Kicker's wiring. The product is extremely well and conductive. Powers both my amplifiers and I have absolutely no flickering or clipping.

Great Wire

I love this wire! I had to shave my "4 gauge" wire from amazon down to fit into 4 gauge slots, while this just goes right in. Nice and easy to work with, flexible, and super hard to cut if you're using a kitchen knife like a lot of other DIYers.
