The Essential Connections, Covered
True Spec 4 Gauge Power
The orange cable shown is the kit’s true spec 4 gauge power cable. Its 17 foot length gives installers useful reach for routing power from the vehicle battery area to an amplifier location in many vehicle layouts. Built for mid to high-power amplifier systems, it supports strong, consistent power output as you plan a complete audio upgrade.
Clean RCA Signal Transfer
The 17 foot RCA cable provides the signal connection between compatible audio components and an amplifier. Double shielding helps minimize interference so the audio signal can travel cleanly through the installation. The extended length supports flexible routing choices, helping keep signal wiring organized while building a system around the vehicle interior.
20 Feet of Speaker Wire
This kit includes a 20 foot speaker wire run for connecting amplifier output to compatible speakers. The bundled cable helps keep a key part of the amplifier installation in one package, so you can plan power, signal, remote turn-on, ground, and speaker connections together. Its length gives added flexibility when mapping cable paths in a range of vehicle types.
Protection and Install Details
The pictured accessory set brings together the components that help finish an organized amplifier wiring installation. An inline ANL fuse holder is supplied with both a 150A ANL fuse and a 200A ANL fuse, allowing the protection option to be selected based on the system setup. The kit also includes terminals, connectors, zip ties, mounting hardware, electrical tape, protective wire loom, and additional installation accessories. Use the included 3 foot ground cable for the amplifier ground connect
Plan a System That Works Together
A satisfying vehicle audio upgrade starts with the connections behind the equipment. The SX4CXL wiring kit helps system builders bring the primary amplifier wiring needs into one coordinated package. With dedicated power, ground, RCA signal, remote turn-on, and speaker wire lengths, it is easier to map the installation before routing cables through the vehicle.
For daily listening, clean signal routing and consistent amplifier power are essential parts of a well-planned setup. The double shielded RCA cable is designed to minimize interference, while the true spec 4 gauge power cable is intended for mid to high-power amplifier systems. The 17 foot power and RCA cable lengths provide flexibility for many common amplifier locations, helping installers create cleaner runs from the front of the vehicle to the audio system.
The kit is designed for more than one kind of build. It is suitable for car, truck, motorcycle, ATV, and RV audio amplifier installations, making it a practical choice when vehicle size and cable-routing needs differ. Match the supplied 150A or 200A ANL fuse to the system setup, route each cable carefully, and use the included accessories to keep the completed installation orderly.
