• 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

• 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 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 gear shift 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 speaker negative 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.
• IP-BUS connectors are color-coded. Be sure to
connect connectors of the same color.
