WR04 - Amplifier Power/ground Input Wire Gauge Reducer Brass 1/0 Gauge to 4 Gauge with Red/black Silicon Covers, Marine-grade Satin Chrome Finish, Pair

The WR04 is a brass wire gauge reducer designed to step down 1/0 gauge amplifier power and ground input wire to a 4 gauge connection. Sold as a pair, these reducers are built for installers who need a clean, reliable transition between wire gauges without splicing or crimping. Marine-grade satin chrome finish makes them a solid choice for both automotive and marine environments.
