RBG3 - True Spec 1/0 Gauge Wire Big 3 Amp Wiring Upgrade Kits for Car Audio Systems

The RBG3 is Recoil Audio's Echo Big 3 Wiring Kit, built for CCA systems up to 250A that need a foundational electrical upgrade before adding amplifier load. It replaces three critical factory wires — battery ground to chassis, chassis to engine block, and alternator positive to battery positive — with true-spec 1/0 AWG CCA cable rated for heat, vibration, and sustained current draw.

• System rating: Designed for car audio systems drawing 250A or less.
• Complete three-wire replacement: Covers battery ground to chassis, chassis to engine block, and alternator positive to battery positive.
• True-spec 1/0 AWG CCA cable: Two 4ft frosted gray cables and one 6ft frosted blue cable, each terminated with copper ring terminals.
• Flexible insulation: Wire jacket resists corrosion, heat, and vibration to protect vehicle components over time.
• Full hardware included: Ten nylon cable clamps, ten 1/2" #8 wafer head Tek screws, ten black zip ties, and three heavy-duty copper ring terminals.
• Addresses headlight dimming: Improves electrical efficiency under high-demand audio loads.
