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.
