To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery's
positive terminal.
Wiring
•Take the battery wire for this unit directly from the battery. If it's connected to the vehicle's
wiring harness, it can cause blown fuses etc.
• 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 wire 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 install a protective fuse in the power cord near the battery. The protective fuse
should be the same capacity as the unit's fuse capacity or somewhat larger.
• For the power cord and ground, use a vehicle type (fireproof) power wring cord with a current
capacity greater than the unit's fuse capacity. (Use a power wiring cord with a diameter of 8
mm
2
(AWG 8) or greater.)
• 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.
