4 Gauge OFC Amplifier Wiring Kit

The Topstronggear TGK-04AC is a complete amplifier installation kit built around 4 gauge oxygen-free copper power and ground cables. It includes 17 feet of blue power wire and 3 feet of white ground wire, each using 1,862 strands for flexibility. A heat-tested, water-resistant inline ANL fuse holder with a 150 amp fuse protects the main power run.

Installers Adding a Single Amplifier

This kit suits anyone wiring one amplifier in a car, truck or marine stereo system who needs power, ground, signal and speaker connections in one package. It provides two-channel RCA interconnects and 14 gauge speaker wire, both 17 feet long. Builders planning multiple amplifiers or requiring additional power distribution blocks should look at a different kit.

150 Amp ANL Fuse Rating

The included fuse holder and 150 amp ANL fuse set the maximum continuous current the main power cable can safely carry. Match this rating to the amplifier manufacturer's recommended fuse value; if the amp calls for a higher or lower fuse rating, this specific kit will not meet that requirement.
