Overview

The Gravity BGR-KIT8-PK3 is a complete 8-gauge amplifier installation wiring kit designed to supply everything needed to connect an aftermarket amplifier in a 12-volt vehicle. The package centers around 17 feet of 8-gauge power cable and 3 feet of 8-gauge ground cable, paired with an inline AGU fuse holder and both 40A and 60A fuses. Signal delivery is handled by a 17-foot double-shielded RCA cable engineered to reject electromagnetic interference, while a 17-foot 18-gauge remote turn-on wire and 20 feet of 16-gauge speaker wire round out the electrical connections. All necessary ring terminals and accessories are included.

This kit is aimed at car, truck, motorcycle, RV, and ATV owners running amplifier systems up to 1000 watts. The bundled components eliminate the guesswork of assembling individual cables and connectors, making it a practical choice for both professional installers working through multiple jobs and first-time DIY enthusiasts. The color-coded cables (red, blue, and black) simplify identification during installation, and the complete accessory set means no extra trips to the parts store for terminals or fuse holders.

Pros & Cons

👍 Pros

  • All-in-one package includes power cable, ground cable, RCA, speaker wire, turn-on wire, fuses, and terminals.
  • Double-shielded RCA cable helps reduce noise and signal interference in the audio path.
  • Includes both 40A and 60A fuses so you can match the fuse rating to your amplifier's requirements.
  • 17-foot cable lengths accommodate most standard vehicle installations without splicing.
  • 8-gauge wiring provides adequate current delivery for amplifier systems up to 1000 watts.

👎 Cons

  • 8-gauge wire may be undersized for amplifiers pushing close to the full 1000W rating continuously.
  • Ground cable is only 3 feet long, which limits flexibility in chassis grounding location.
  • Speaker wire is 16-gauge, which may not be sufficient for longer runs or higher-power speaker loads.
  • Cable material is copper-clad rather than full oxygen-free copper, which can affect long-term conductivity.
