Complete 3500W Gravity 4 Gauge Amplifier Wiring Kit - All-In-One

Our review of the Complete 3500W Gravity 4 Gauge Amplifier Wiring Kit finds it best suited for installers and experienced DIY hobbyists who need a single, heavy-duty kit that covers power, ground, signal, and speaker wiring. The standout reason to buy is the thick 17 ft 4 gauge power cable paired with a premium 3 ft 4 gauge ground and built-in ANL fuse options, which together deliver robust current capacity and cleaner installs. This kit is a practical, no-surprise solution for car, truck, motorcycle, RV, and ATV audio projects.

Key Features

• 4 gauge power cable: A 17 ft 4 gauge power cable provides heavy-duty current capability for high-power amplifiers and flexible routing in most vehicles.
• Ground and fuse protection: The 3 ft 4 gauge ground cable plus inline ANL fuse holder and both 200A and 300A fuses give installers options for safe, matched protection.
• Double shielded RCA: The 17 ft double shielded RCA cable helps reduce noise and preserves cleaner signal transfer from head unit to amplifier.
• Accessory coverage: Included terminal hardware, turn-on cable and speaker wire mean the kit covers every basic connection needed for an amplifier install.
• Turn-on and speaker wiring: The 17 ft/18 ga turn-on lead and 20 ft/16 ga speaker wire simplify wiring in longer vehicles or when routing to remote amps or enclosures.

Who It's For

The kit is aimed at professional installers and competent DIYers who plan to run a substantial amplifier setup up to the kit's implied 3500W class and who value having a complete wiring set without sourcing each part separately. The heavy 4 gauge power and ground conductors suit installations where voltage drop must be minimized.

Those looking for ultra-high current systems beyond what a single 4 gauge feed and the included fuses can safely support, or installers who require custom length or exotic connectors, may prefer to choose individual components tailored to their exact power and fuse specifications.

Pros & Cons

Pros
