Let's Power Up! Everyone needs a good sidekick, and your amplifier is no exception. To give your amplifier the power and support it needs, there is no better choice than NVX. When designing our amp kits, we had just three things in mind - durability, usability, and performance. We think our kits look great, and you won't find the silly marketing gimmicks others have become infamous for. When you use NVX, you will have the confidence of knowing you are using the best amplifier installation kit available. Tough, Rugged Wire NVX amp kits are built using materials that are not only of the highest quality, but also specifically engineered to provide optimal performance in the harsh vehicle environment. The durable EnvyFlex jacket offers superior flexibility and routing options, all while keeping the wire properly insulated. For added protection against chafing, the wire is terminated with 6 feet of nylon braided jacketing. Maximum Power Transfer The power & ground wire in your NVX amp kit is constructed with Silver-Tinned 100% Oxygen-Free Copper. By using these pure, highly conductive materials, we ensure that our amp kits can transfer massive amounts of power from the battery to your amplifier without overheating. The fuse holder & distribution blocks are made of satin chrome-plated brass, which easily tolerates the heat & vibration in the engine bay without corroding. The wires are held tightly by strong hex-head set screws, while the durable ABS cover insulates the terminals & prevents short-circuits. All spade terminals and set screws are nickel-plated for maximum power transfer. WHAT'S IN THE BOX: 20 ft. (6.1 meters) Frosted Blue 1/0 gauge power wire with seamless crimp ring terminal 3 ft.
