PCK4D - True 4 Gauge 99.99% Oxygen Free Copper Car Audio Dual Amplifiers Complete Installation Wiring Kits

The PCK4D Echo Pro is a dual-amplifier OFC wiring kit built around a 4 AWG main power run, giving you the headroom to feed two amplifiers cleanly from a single installation. Every conductor in the kit — power, ground, RCA, and speaker wire — is true oxygen-free copper, minimizing resistance and signal loss across the entire chain. Solid brass ANL/Mini-ANL fuse holders with satin chrome plating and 6 feet of nylon braided sleeving on the main power wire round out a kit engineered for lasting, heat-tolerant installs.

• True OFC throughout: Power, ground, RCA interconnects, and speaker wire are all genuine oxygen-free copper — no copper-clad aluminum shortcuts.
• Dual-amp ready: Includes two DB14 distribution blocks and split 8 AWG secondary runs to power a second amplifier off the same 4 AWG main feed.
• Fusing and surge protection: Brass ANL/Mini-ANL fuse holder ships with a 100A ANL fuse; additional 80A and 120A ANL fuses are included for system flexibility.
• Heat and abrasion protection: Main power wire is pre-wrapped in 6 feet of nylon braided tubing for engine bay routing.
• Complete hardware package: Nickel-plated spade terminals, a rubber firewall grommet, butt connectors, speaker terminals, and zip ties are all included.
