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 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.
• Please be sure to install a protective fuse in the power wire, near the battery. Use a fuse which
has a capacity about 10A higher than the capacily of the fuse in the unit.
• For the power wire and the earth wire, use (flame-resistant) power wiring wires for in-car use. For
the power wire, use a power wiring wire 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 wier and
protective fuse of greater current-handling capacity than the total maximum current drawn by each
amplifier.
