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.
