AUDIO360 AD4C 4 Gauge Amplifier Wiring Kit

The AUDIO360 AD4C is a 4 AWG amplifier wiring kit for routing power, signal, remote turn-on, and speaker connections in a vehicle audio installation. It provides the core cable lengths and protection hardware needed when adding an amplifier to a car, truck, SUV, motorcycle, ATV, or RV. The kit is intended for installers replacing incomplete wiring or building an amplifier system from the ground up.

A True Spec 4 AWG power cable serves as the primary power connection between the battery area and amplifier. The included 17-foot length supports common vehicle cable-routing paths, while the separate 3-foot ground cable is intended for a short chassis-ground connection. Properly sized power and ground wiring are important parts of a dependable amplifier installation.

For audio signal routing, the AD4C includes a 17-foot double-shielded RCA cable. Its shielding is designed to help reduce interference that can enter low-level audio signal wiring in a vehicle. A 17-foot remote wire is also included to connect the amplifier's turn-on lead to a compatible source unit or signal interface.

The kit includes an inline AGU fuse holder with both 80A and 100A AGU fuses. These fuse options provide flexibility when selecting circuit protection appropriate to the connected amplifier system. Fuse selection and installation should follow the amplifier manufacturer's requirements and be placed close to the battery-side power connection.

A 20-foot speaker wire is included for connecting an amplifier to speakers or a subwoofer system. With power cable, ground cable, signal cable, remote wire, fuse protection, and installation accessories included, the AD4C helps consolidate the main wiring items for an amplifier project. It is a practical fit for entry-level and mid-level vehicle audio upgrades using 4 AWG power wiring.

Key Features

• True Spec 4 AWG Power Cable: Provides the primary power run for an amplifier installation.
• 17-Foot Power Cable: Offers length for common vehicle battery-to-amplifier routing.
• Double-Shielded RCA Cable: Helps reduce interference in the low-level audio signal path.
• AGU Fuse Protection: Includes an inline fuse holder for battery-side circuit protection.
• Two Included Fuse Ratings: Supplies both 80A and 100A AGU fuses.
• Complete Wiring Assortment: Includes power, ground, RCA, remote, speaker wire, and accessories.

Design & Installation

The AD4C combines 4 AWG power wiring, a dedicated ground cable, a double-shielded RCA cable, remote wire, speaker wire, and an AGU fuse holder in one installation package. Its cable lengths are arranged around typical amplifier installations, with a long power run and a shorter ground lead. The included fuse holder supports AGU-style fuses and is supplied with two fuse ratings.

Route the power cable separately from RCA signal wiring where practical, and keep the ground connection short and securely attached to clean vehicle chassis metal. Install the fuse holder close to the battery connection, then select the 80A or 100A fuse only according to the amplifier maker's specified protection requirement. Confirm that the amplifier accepts 4 AWG power wiring and that all vehicle-specific routing, termination, and safety requirements are met before installation.
