Power cable connection
To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the
battery’s positive terminal.

Power terminal
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.
