PPK4 - True 4 Gauge 99.99% Oxygen Free Copper Power Installation Wiring Kits

The Echo Pro PPK4 is a complete 4 gauge OFC amplifier wiring kit built for installers who won't compromise on signal integrity or long-term reliability. Every conductor — power, ground, RCA, and speaker wire — is true-to-gauge 99.99% oxygen-free copper, eliminating the resistance and signal loss common in CCA-based kits. The flexible outer jacket and included nylon braided sleeve make clean, professional routing straightforward even in tight engine bays.

• True 4 Gauge OFC Throughout: Power, ground, and remote wires are genuine 99.99% oxygen-free copper — not CCA — for maximum conductivity and minimal power loss.
• Protected Power Wire: 17ft of 4 gauge OFC red power wire ships pre-wrapped in 6ft of nylon braided tubing for heat and chafe resistance in the engine bay.
• Solid Brass ANL Fuse Holder: Satin chrome-plated brass construction with a 100A ANL fuse installed; 80A and 120A spares included for system flexibility.
• Nickel-Plated Terminations: Spade terminals and connectors use nickel plating for corrosion resistance and consistent long-term signal transfer.
• Complete Installation Hardware: Includes firewall grommet, zip ties, screw/washer, butt connectors, and ring terminals — everything needed for a clean single-amplifier install.
