Protective
Fuse
To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s
positive terminal.
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 wire.
• Do not allow the cord to directly contact the edge of the iron plate by using Grommets.
• Connect the ground wire 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
wire is not connected.
• Be sure to attach a protective fuse into the battery wire 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 wire for the battery wire and the ground wire.
The current capacity of the power supply wiring wire 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 wire and
protective fuse of greater current-handling capacity than the total maximum current drawn by each
amplifier.
Power terminal
Connect to their respective terminals the power control wire, power supply wire, and ground
wire, all of which pass through the associated terminal cover. Once the connections are
complete, place the cover on the terminal section.
