The Phoenix Gold ZXK20 amplifier wiring kit is a heavy-duty car audio power kit designed for systems up to 1500W RMS. It uses ultra-pure oxygen-free copper conductors in 20mm2 cable, equivalent to approximately 4 AWG, to maximize current flow and reduce resistance.

The kit includes OFC power and ground cable, shielded RCA interconnects, a fuse holder with fuse, remote turn-on wire, terminals, cable ties and grommets for a complete installation. It is suited for mid-to-high powered aftermarket amplifiers and subwoofer systems.
