WARNING
• Use speakers over 50 W (output
value) and between 4 Ω to 8 Ω
(impedance value). Do not use 1 Ω to
3 Ω speakers for this unit.
• The black cable is ground. When
installing this unit or power amp
(sold separately), make sure to
connect the ground wire first. Ensure
that the ground wire is properly
connected to metal parts of the car's
body. The ground wire of the power
amp and the one of this unit or any
other device must be connected to
the car separately with different
screws. If the screw for the ground
wire loosens or falls out, it could
result in fire, generation of smoke or
malfunction.

or malfunction.
– Vehicles with a 12-volt battery and
negative grounding.
– When speaker output is used by 4
channels, use speakers over 50 W
(maximum input power) and
between 4 Ω to 8 Ω (impedance
value). Do not use 1 Ω to 3 Ω
speakers for this unit.
– When rear speaker output is used
by 2 Ω of subwoofer, use speakers
over 70 W (maximum input power).
* Please refer to connection for a
connection method.
• To prevent a short-circuit,
overheating or malfunction, be sure
to follow the directions below.
– Disconnect the negative terminal
of the battery before installation.
– Secure the wiring with cable
clamps or adhesive tape. Wrap
adhesive tape around wiring that
comes into contact with metal
parts to protect the wiring.
– Place all cables away from moving
parts, such as the shift lever and
seat rails.
– Place all cables away from hot
places, such as near the heater
outlet.
– Do not connect the yellow cable to
the battery by passing it through
the hole to the engine
compartment.
– Cover any disconnected cable
connectors with insulating tape.
– Do not shorten any cables.
– Never cut the insulation of the
power cable of this unit in order to
share the power with other devices.
The current capacity of the cable is
limited.
– Use a fuse of the rating prescribed.
– Never wire the negative speaker
cable directly to ground.
– Never band together negative
cables of multiple speakers.
• When this unit is on, control signals
are sent through the blue/white
cable. Connect this cable to the
system remote control of an external
power amp or the vehicle's auto-
antenna relay control terminal (max.
300mA 12 V DC). If the vehicle is
equipped with a glass antenna,
connect it to the antenna booster
power supply terminal.
• Never connect the blue/white cable
to the power terminal of an external
power amp. Also, never connect it to
the power terminal of the auto
antenna. Doing so may result in
battery drain or a malfunction.
• The black cable is ground. Ground
cables for this unit and other
equipment (especially, high-current
products such as power amps) must
be wired separately. If they are not,
an accidental detachment may result
in a fire or malfunction.
