Before connecting the
amplifier
AWARNING
• Secure the wiring with cable clamps or adhe-
sive tape. To protect the wiring, wrap sections
in contact with metal parts in adhesive tape.
•
Never cut the insulation of the power supply
to feed power to other equipment. Current ca-
pacity of the wire is limited.
A
CAUTION
•
Never shorten any wires, the protection circuit
may malfunction.
•
Never wire the speaker negative cable directly-
to ground.
•
Never band together multiple speaker'snega-
tive cables.
•
If the system remote control wire of the ampli-
fier is connected to the power terminal via the
ignition switch (12 V DC), the amplifier will re-
main on with the ignition whether the car
stereo is on or off, which may exhaust battery
if the engine is at rest or idling.
