STX Audio SX0C 0 AWG Amplifier Wiring Kit

The STX Audio SX0C is a complete 0 AWG amplifier wiring kit designed to supply power, signal wiring, remote turn-on wiring, speaker wire, and circuit protection for a car-audio amplifier installation. It brings the major cable runs together in one package for installers building or upgrading a high-current audio system. The kit is intended for use where a true-spec 0 AWG power cable is appropriate for the amplifier and electrical system.

A 17-foot power cable and 3-foot ground cable provide the primary power path between the vehicle battery, amplifier, and chassis grounding point. The included ANL fuse holder supports system protection near the power source. Both 200-amp and 250-amp ANL fuses are included so the installer can select the listed fuse option that suits the system requirements.

For source-to-amplifier signal routing, the SX0C includes a 17-foot double-shielded RCA cable. Its shielding is intended to support a clean signal path in a vehicle environment where power and accessory wiring may be nearby. A 17-foot remote turn-on wire is also included to connect the source unit's remote output to a compatible amplifier.

The kit also includes 20 feet of speaker wire for connecting an amplifier to speakers or a subwoofer enclosure. These cable lengths are suited to many front-to-rear amplifier layouts in cars, trucks, SUVs, and similar vehicles. Actual routing needs should be measured before installation, especially in larger vehicles or custom systems.

The SX0C is a practical foundation for an amplifier installation rather than an audio component with its own sound tuning. It is intended for system builders who need a coordinated wiring package with large-gauge power cable, RCA interconnects, speaker cable, and an ANL protection solution. Match the fuse selection, cable routing, and amplifier connection requirements to the vehicle and amplifier manufacturer instructions.

Key Features

• True-Spec 0 AWG Power Cable: Provides a large-gauge primary power connection for compatible high-current amplifier installations.
• 17-Foot Power Cable: Gives installers substantial length for battery-to-amplifier routing in many vehicle layouts.
• ANL Fuse Holder: Adds an inline circuit-protection point to the amplifier power-wire run.
• Two Included ANL Fuses: Includes 200A and 250A fuse options for system-specific protection selection.
• Double-Shielded RCA Cable: Supports signal routing from a source unit to a compatible amplifier.
• Complete Cable Package: Includes power, ground, RCA, remote, and speaker wiring in one kit.

Design & Installation

The SX0C is organized around a true-spec 0 AWG power cable, a separate short ground cable, a fused ANL power connection, and dedicated signal and speaker wiring. The double-shielded RCA cable is designed for vehicle audio signal routing, while the included remote wire supports amplifier turn-on integration. This component selection helps keep the principal amplifier wiring functions within one coordinated kit.

Route the power cable through a protected firewall pass-through and install the ANL fuse holder close to the battery according to vehicle and amplifier instructions. Use the 3-foot ground cable for a short, secure chassis ground connection, and route RCA signal cables separately from the main power cable where practical. Confirm the amplifier's required wire size and fuse rating before selecting either included fuse and completing the installation.
