Overview

The Gravity BGR-KIT0-B-PK3-4000W is a complete 0-gauge amplifier installation wiring kit built for high-powered car audio systems. It includes 17 feet of 0-gauge power cable for the battery-to-amplifier run, 3 feet of 0-gauge ground cable, 17 feet of double-shielded RCA interconnect cable, 17 feet of 18-gauge remote turn-on wire, and 20 feet of 16-gauge speaker wire. An inline ANL fuse holder with a 250-amp fuse is also included, providing critical overcurrent protection for the amplifier circuit. All necessary ring terminals and connectors come in the box, so there is no need to source hardware separately.

This kit is designed for 12-volt vehicle applications and works in cars, trucks, motorcycles, RVs, and ATVs. The 0-gauge cable thickness makes it appropriate for amplifiers drawing significant current — generally systems in the 2000- to 4000-watt range. The double-shielded RCA cable is a practical inclusion that helps keep engine noise out of the audio signal, which is a common issue in car audio installations. While the kit covers the essentials for a single-amplifier setup, users running multiple amplifiers or needing longer ground runs may need to supplement with additional cable.

Pros & Cons

👍 Pros

  • 0-gauge cable handles high-current loads for amplifiers rated up to 4000 watts.
  • Comprehensive kit includes power cable, ground cable, RCA, speaker wire, turn-on wire, fuse holder, and terminals in one package.
  • Double-shielded RCA cable helps minimize engine noise and signal interference.
  • 17-foot power and RCA cable lengths accommodate most vehicle installations without splicing.

👎 Cons

  • The 3-foot ground cable may be too short if the amplifier is mounted far from a suitable grounding point.
  • Only 20 feet of 16-gauge speaker wire is included, which may not be enough for multi-speaker setups.
  • The 250A fuse may not be the correct rating for all amplifiers — some setups require a different fuse value.
  • Cable quality at this price point may not match premium audiophile-grade wiring kits.
