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.
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.
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.

Great Value
Best price per foot out there. Very good quality, real OFC and not CCA. Nice looking covering.

NVX XW4 Wire
This Wire is a Copper Beast. The weight alone will confirm the difference between this and the Copper Clad Aluminum less expensive alternative. If aluminum wire or tinned wire is used, the gauges should be of an even larger size to compensate. ANY Power Drop will affect the Amp, and over time possibly a resistor or capacitor, A Dremel with a cut-off wheel and solder the Copper connector rather than attempting to crimp to give it a clean, solid appearance.

Great wire value
I chose NVX for all my wiring needs; from the silver tinned OFC for power, ground, and speaker wires, to the RCAs. After my research, these were the wires to get; and the pricing here is great.

Tru 4 AWG wire
No problems here. This stuff is a bit cheaper than the Rockford stuff so I gave it a chance. I bought 2 20' sections so I can customized my installation a little better. This is the quality you want in your car.
