WARNING
• 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 connections for a
connection method.
• 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

• Use this unit with a 12-volt battery
and negative grounding only.
Failure to do so may result in a fire
or malfunction.
• 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. 300 mA 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 graphical symbol placed
on the product means direct
current.
