Overview

The Gravity BGR-KIT4-B-PK2-3500W 4 Gauge Amplifier Installation Wiring Kit is a comprehensive package that provides everything needed to wire an aftermarket amplifier into a vehicle's audio system. The kit centers on a 17-foot run of 4-gauge power cable paired with a 3-foot 4-gauge ground cable, both essential for delivering clean, stable power to your amplifier. An inline ANL fuse holder is included along with both 200A and 300A fuses, giving installers the flexibility to choose the right level of overcurrent protection for their specific amplifier.

On the signal side, a 17-foot double-shielded RCA cable carries audio from the head unit to the amplifier while minimizing electromagnetic interference and engine noise. The kit also includes a 17-foot 18-gauge remote turn-on wire for triggering the amplifier on and off with the head unit, plus 20 feet of 16-gauge speaker wire for connecting the amplifier output to speakers. All necessary ring terminals, connectors, and mounting accessories are included, making this kit suitable for professional installers and DIY enthusiasts working on cars, trucks, motorcycles, RVs, and ATVs.
