metra gauge amp kit

Metra marine amp kits include 4-gauge and 8-gauge power wiring, covering common marine amplifier installations.

Power-wire lengths are typically offered as 10 feet or 20 feet across the available Metra amp kits.

Power cable is described as fully tinned 100% virgin copper, and the RCA interconnects use tinned oxygen‑free copper (OFC) conductors — both selected for improved corrosion resistance and conductivity.

The remote turn‑on wire is listed as 18 feet, and many kits include pre‑terminated ring terminals with shrink tube on the power and ground leads.

RCA cables use tinned OFC conductors with polyethylene dielectrics arranged in a high‑rate twisted‑pair configuration, and feature molded connectors with nickel‑plated brass contacts to help reject noise and resist corrosion.
