• 【Big 3 Upgraded Wire】Our Big 3 upgraded wiring harness creates an ultra-low resistance "electric highway" (battery negative to chassis ground, engine block to chassis ground, and alternator positive to battery) for your generator, engine, and battery by using heavy-duty 1/0 gauge (0 AWG) pure copper wire.This stabilizes voltage, minimizes power loss, and enhances audio performance, headlight brightness, and overall electrical system response.
• 【100% Pure Copper】Three 0 gauge cable (power wire x1, ground wires x2) are made up of 1805 high-purity oxygen free copper wires with a diameter of 0.19mm twisted together. OFC structure not only provides stronger current carrying capacity, high conductivity, improved system efficiency, but also reduced load on the vehicle’s electrical system，to lay a solid foundation for achieving high fidelity sound quality.One end is pre-assembled with an SC70-8 tinned copper terminal. The tin plating prevents oxidation, enhances corrosion resistance.
• 【Sturdy & Durable】Made of high-quality PVC material, compliant with UL 1015 standard, with an outer diameter of 14mm. Rated for 600V and withstands temperatures from -40°C to 105°C. It offers good resistance to oil, chemicals, moisture, and aging, ensuring safe and stable operation even in harsh environments.Features an ultra-flexible insulation layer that bends easily for simple installation, ideal for narrow spaces and tight corners.
• 【Package Includes】6 ft 1/0 AWG power wire x1; 24 ft 1/0 AWG ground wire x2(0 gauge cable has one end with ring terminal and one end pre-stripped);Extra terminals (SC70-8) x3; Heat shrink tubes x5;Black nylon wire clamps x10; Self-tapping wafer head Tek screws x10; Cable ties x25; 15 meter Fabric adhesive tape x1
• 【Widely Application】Big 3 Complete Upgrade Electrical Wiring Kit not only suitable for upgrading car audio systems but also for enhancing the overall electrical system foundation of off-road vehicles, trucks, RVs, or ships, solving the problem of insufficient voltage caused by the original factory wire diameter being too thin.If you have any questions about our product, please feel free to contact with our reliable customer service, we will reply you within 24 hours.
