Before connecting the
amplifier
A
wARNING
•
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 ground speaker wire directly or band to-
gether multiple speakers' negative (8) lead
wires.
•
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.
•
Install 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.[!)
