Authorized dealer

100% Oxygen-Free Copper 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.

Frequently Asked Questions (FAQ)


Yes. For high-power systems, grounds should be under 3 feet to minimize resistance. This 5ft section is the perfect solution for grounding 2000W+ amplifiers to a solid chassis point to prevent clipping or overheating.
Yes. The silver-tinned copper resists corrosion in engine bays. Replacing your factory battery-to-chassis ground with this 1/0 OFC will stabilize your charging system and is a permanent solution for headlight dimming.
Do not trim the copper strands to make it fit. Instead, use an NVX 1/0 to 4-gauge reducer. This allows you to maintain the massive current capacity of the 1/0 wire while cleanly and safely adapting it to a smaller terminal.
Yes. The EnvyFlex PVC jacket is engineered to be oil, gas, and heat resistant. It remains flexible even in freezing temperatures, making it the ideal solution for routing through tight grommets or around engine components.
No. Fuses are for Positive (+) power runs. For a ground wire, ensure the connection point is scraped to bare metal. Use an NVX 1/0-gauge ring terminal and a star washer to create a permanent, zero-resistance connection.

Quality, pure 100% copper wires!!

These are a must with any system that's running over 1000 watts of clean power. Wether upgrading the big 3 on your vehicle or powering over 1000 watts of insane power to your speakers, these cables are the easiest to route and most user friendly that you can buy without breaking the bank. It's a must for any aftermarket installation.
