• Make sure that the cables and wires will
not interfere with or become caught in
any of the vehicle's moving parts,
especially the steering wheel, shift lever,
parking brake, sliding seat tracks, doors,
or any of the vehicle's controls.
• Do not route wires where they will be
exposed to high temperatures. If the
insulation heats up, wires may become
damaged, resulting in a short circuit or
malfunction and permanent damage to
the product.
• Do not shorten any leads. If you do, the
protection circuit (fuse holder, fuse
resistor or filter, etc.) may fail to work
properly.
• Never feed power to other electronic
products by cutting the insulation of the
power supply lead of this product and
tapping into the lead. The current
capacity of the lead will be exceeded,
causing overheating.
Before installing this
product
• Use this unit with a 12-volt battery and
negative grounding only. Failure to do so
may result in a fire or malfunction.
• To avoid shorts in the electrical system,
be sure to disconnect the (–) battery
cable before installation.
To prevent damage
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.
• 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.

disconnected lead with insulating tape. It
is especially important to insulate all
unused speaker leads, which if left
uncovered may cause a short circuit.
• For connecting a power amp or other
devices to this product, refer to the
manual for the product to be connected.
• The graphical symbol

the product means direct current.
Notice for the blue/
white lead
• When the ignition switch is turned on
(ACC ON), a control signal is output
through the blue/white lead. Connect to
an external power amp's system remote
control terminal, the auto-antenna relay
control terminal, or the antenna booster
power control terminal (max. 300 mA 12
V DC). The control signal is output
through the blue/white lead, even if the
audio source is switched off.
