Connect to their respective terminals the power control cable, power supply cable, and ground cable, all of which pass through the associated terminal cover. Once the connections are complete, place the cover on the terminal section.

Wiring

If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery cable.

Do not allow the cord to directly contact the edge of the iron plate by using Grommets.

Connect the ground cable to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery‘s negative - terminal. Do not turn the power on if the ground cable is not connected.

Be sure to attach a protective fuse into the battery cable close to the battery. Use a protective fuse having a capacity that is about 10 A higher than the maximum current drawn by the amplifier.

Use vehicle-type (fire-resistant) power supply wiring cable for the battery cable and the ground cable. The current capacity of the power supply wiring cable should be about 10 A higher than that of the protective fuse capacity (which means about 20 A higher than the maximum current drawn by the amplifier).

When more than one power amplifier are going to be used, use a power supply wiring cable and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.
