PBG3-4 True Spec 4 Gauge 99.99% Oxygen Free Copper Wire Big 3 Amp Wiring Upgrade Kits for Car Audio Systems up to 200 Amps

The Big 3 Upgrade If you’re a car audio enthusiast, eventually your sound system will reach the point where it is too powerful for your vehicle’s existing electrical system. The first step in upgrading your power system should be a Big 3 Upgrade, and there is no better Big 3 kit than Recoil PBG3 & PBG3-4. Our Big 3 Upgrade kit is specifically designed to help your old electrical system cope with the demands of your fantastic sound system and help with those annoying dimming headlights when your sound really kicks. Our kits are engineered from the highest quality materials to ensure long lasting durability. Included with the kit are the battery ground to chassis wire, the chassis to engine block wire and the alternator positive to battery positive wire as well as the clamps, screws and copper ring terminals necessary with this installation. The highly conducive 99.99% Oxygen Free Copper wire provides optimal performance in even the harshest environments. It allows your electrical system to run at its maximum efficiency while also allowing your amps to run cooler and subs to hit harder.     Flexibility Recoil 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 passage ways 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 electrical 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 Recoil 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.
