About: Skar Audio SKBIG3-4GA 4 Gauge "Big 3" OFC Wiring Upgrade Kit

When looking to improve the electrical system in your vehicle, the obvious starting point is with upgrading what is commonly referred to as the "Big 3" wiring. This Skar Audio 1/0 gauge wiring upgrade kit (SKBIG3-0GA) includes everything you need to complete the "Big 3", allowing for a hassle free installation. 

The cables come pre-terminated with 3/8" copper lugs attached and heat shrink already applied, ultimately saving hours of end-user preparation work. To finish the connections on the other side of the cables, we include 3 additional copper lugs and the heat shrinks. Lastly, we include multiple install accessories, including zip ties and cable clamps which are paired with wafer head screws, allowing wires to be safely secured.
