Before conneding 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.
AcAUTION
• Never shorten any wires, the protection circuit
may malfunction.
• Never wire the speaker negative cable directly
to ground.
• Never band together multiple speaker's nega-
tive cables.
• If the system remote control wire of the ampli-
fier is connected to the power terminal via the
ignition switch (12V 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.
• I nstal I and route the separately sold battery
wire as far as possible from the speaker wires.
Install and route the separately sold battery
wire, ground wire, speaker wires and the am-
plifier as far away as possible from the anten-
na, antenna cable and tuner.
