Note:
• This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recre-
ational vehicle, truck or bus, check the battery
voltage.
• To avoid shorts in the electrical system, be sure to
disconnect the
≠
battery cable before beginning
installation.
• Refer to the owner’s manual for details on con-
necting the power amp and other units, then make
connections correctly.
• Secure the wiring with cable clamps or adhesive
tape. To protect the wiring, wrap adhesive tape
around them where they lie against metal parts.
• Route and secure all wiring so it cannot touch any
moving parts, such as the gear shift, handbrake and
seat rails. Do not route wiring in places that get
hot, such as near the heater outlet. If the insulation
of the wiring melts or gets torn, there is a danger of
the wiring short-circuiting to the vehicle body.
• Don’t pass the yellow lead through a hole into the
engine compartment to connect to the battery. This
will damage the lead insulation and cause a very
dangerous short.
• Do not shorten any leads. If you do, the protection
circuit may fail to work when it should.
• Never feed power to other equipment by cutting
the insulation of the power supply lead of the unit
and tapping into the lead. The current capacity of
the lead will be exceeded, causing overheating.
• When replacing the fuse, be sure to only use a fuse
of the rating prescribed on this unit.
• Since a unique BPTL circuit is employed, never
wire so the speaker leads are directly grounded or
the left and right
≠
speaker leads are common.
If you ground the products together and the ground
becomes detached, there is a risk of damage to the
products or fire.
• The black lead is ground. Please ground this lead
separately from the ground of high-current prod-
ucts such as power amps.
If you ground the products together and the ground
becomes detached, there is a risk of damage to the
products or fire.
• Speakers connected to this unit must be high-
power with minimum rating of 50 W and imped-
ance of 4 to 8 ohms. Connecting speakers with out-
put and/or impedance values other than those
noted here may result in the speakers catching fire,
emitting smoke, or becoming damaged.
• When this product’s source is switched ON, a con-
trol signal is output through the blue/white lead.
Connect to an external power amp’s system remote
control or the car’s Auto-antenna relay control ter-
minal (max. 300 mA 12 V DC). If the car features
a glass antenna, connect to the antenna booster
power supply terminal.
• When an external power amp is being used with
this system, be sure not to connect the blue/white
lead to the amp’s power terminal. Likewise, do not
connect the blue/white lead to the power terminal
of the auto-antenna. Such connection could cause
excessive current drain and malfunction.
• To avoid a short-circuit, cover the disconnected
lead with insulating tape. Insulate the unused
speaker leads without fail. There is a possibility of
a short-circuit if the leads are not insulated.
• If this unit is installed in a vehicle that does not
have an ACC (accessory) position on the ignition
switch, the red lead of the unit should be connected
to a terminal coupled with ignition switch ON/OFF
operations. If this is not done, the vehicle battery
may be drained when you are away from the vehi-
cle for several hours. (Fig. 1)

• Cords for this product and those for other prod-
ucts may be different colors even if they have the
same function. When connecting this product to
another product, refer to the supplied manuals of
both products and connect cords that have the
same function.
