100% Copper, True Spec 4 Gauge Single Amplifier Wiring Installation Kit with Speaker Cable (No RCA)

Power Up!

Looking for a true 4 gauge amp wiring kit? NVX is proud to introduce the XAPK4 4 Gauge Single Amplifier Wiring Installation Kit. This package includes everything you'll need, including speaker wire, to get your amp powered-up properly and running at its peak efficiency.

NVX engineers chose to utilize top-quality materials throughout the kit, including true 100% oxygen-free, silver-tinned copper amp power, ground, and speaker wire. This full copper wire helps prevent signal and power loss through the entire audio system, allowing your amplifier and components to operate to their fullest. The ultra-durable, EnvyFlex outer jacket makes installation and routing of the cable a breeze.

The superior quality and materials of NVX also show in the included accessories. Working in concert with the wire is an NVX XMANL04 solid brass and satin chrome-plated ANL/Mini-ANL Fuse holder with a 100 amp Mini-ANL fuse, protecting you from costly power surges or grounding issues. The power wire comes wrapped in 6 feet of durable nylon braided tubing to protect it from heat and chafing in the engine bay. Even simple installation accessories such as the spade connectors are nickel-plated for superior long-term durability and signal transfer.

 If you're in need of car audio accessories that are built to perform and last, look no further than NVX.


NVX stranded wire is extremely tolerant of the rough conditions in vehicles and compensates for vibration, heat expansion and flexibility. This flexible but well-shielded wire is crucial for getting through all of the nooks and passageways within the cramped confines of vehicle interiors.


Cable Thickness

The thickness of the actual wire, not the insulation, is critical when it comes to transferring the extraordinary current of your audio system. With hundreds of strands of wire in one cable, you get an increased current flow and a higher amperage carrying capacity with a reduced cable size.

Insulation Material

EnvyFlex insulation hinders electric current from exiting the wire prematurely which prevents electrocution and damage to components within the vehicle. Additionally, the insulation maintains the flexibility of the wire while preventing corrosion and damage in the hostile vehicle environment.

Bundled Copper Wires

In an attempt to beef up their wires, some manufactures use all-aluminum or mix copper and aluminum to give the appearance of a quality cable. NVX wire is 100% oxygen-free, silver tinned copper which reduces corrosion increases current transfer, and won’t discolor the insulation of the wire.


NVX wire is hefty and strong, but not overly shielded to increase its weight. A quality cable just feels right with a perfect size to weight ratio that leaves it easy to handle but rugged enough to perform its duties.
