Overview

The Gravity BGR-KIT4-R-PK2-3000W is a complete 4 gauge amplifier installation wiring kit designed to simplify the process of connecting an aftermarket amplifier in any vehicle. The kit centers around 17 feet of 4 gauge power cable — enough length to route from the battery to the trunk in most cars and trucks — paired with a 3-foot 4 gauge ground cable for a solid chassis connection. An inline ANL fuse holder with a 200-amp fuse is included to protect the electrical system and amplifier from overcurrent situations.

On the signal side, a 17-foot double-shielded RCA cable carries audio from the head unit to the amplifier while minimizing electromagnetic interference that can introduce noise into the system. The kit also includes 17 feet of 18 gauge remote turn-on wire to trigger the amplifier with the head unit, and 20 feet of 16 gauge speaker wire for connecting the amplifier to your speakers. All necessary ring terminals, connectors, and installation accessories are included, making this a true all-in-one solution for professional installers and DIY enthusiasts working on cars, trucks, motorcycles, RVs, and ATVs.
