Connection
■ 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.
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 cable 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.
• Please be sure to install a protective fuse in the power cable, near the battery. Use a fuse which
has a capacity about 10A higher than the capacity of the fuse in the unit.
• For the power cable and the earth cable, use (flame-resistant) power wiring cables for in-car use.
For the power cable, use a power wiring cable with a current capacity about 10A higher than the
capacity of the protective fuse (about 20A higher than the capacity of the fuse in the unit).
• 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.
