Connecting the Units <ENGLISH>
Note:
• This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recreational 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 connecting 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 fuse, be sure to use only fuse of
the rating prescribed on the fuse holder.
• 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.
• Speakers connected to this unit must be highpower types with minimum rating of 40 W and
impedance of 4 to 8 ohms. Connecting speakers
with output 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
control 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 terminal (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 short-circuiting, cover the disconnected
lead with insulating tape. Especially, insulate the
unused speaker leads without fail. There is a possibility of short-circuiting if the leads are not insulated.
• To prevent incorrect connection, the input side of
the IP-BUS connector is blue, and the output side
is black. Connect the connectors of the same colors correctly.
•
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 vehicle for several hours.

• The black lead is ground. Please ground this lead
separately from the ground of high-current products 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.
• When there is no place surrounding this unit in
which to ground and you wish to extend the black
lead, use a cable with the same or greater thickness (official conductor area of 3.0mm2) as the
black lead and connect firmly to a metal portion
of the vehicle.

CAUTION:
The default output settings values for this unit are
40W × 4ch. When using this unit at 60W × 4ch you
must adjust the settings switch on the bottom of this
unit. (Fig. 2)
Fig. 2
Follow the below upon connecting with the output settings for this unit set at 60W × 4ch. Connecting with
any other method may result in malfunction.
• Connect the accessory (long red lead) to an accessory circuit of 10A or more when the vehicle
engine switch is set to the ACC position. If the
current is less than 10A the accessory fuse on the
vehicle may be interrupted.
• If this unit is installed in a vehicle that does not
have an ACC (accessory) position on the ignition
switch, install a switch to turn on/off the ACC.
• Connect the battery (yellow lead) to a battery
circuit of 10A or more despite if the vehicle engine
switch is ON or OFF. If the current is less than 10A
the battery fuse on the vehicle may be interrupted.
• If the accessory fuse for the vehicle is less than
10A, use a battery cable such as the RD-221 (sold
separately) for the accessory (long red lead) and
feed the electricity directly from the battery.
• When feeding electricity directly from the battery
for the accessory (long red lead) through a battery
cable, connect the accessory (short red lead) to the
accessory circuit for the vehicle being supplied with
electricity while the vehicle engine switch is set to
the ACC position.
• If the battery fuse for the vehicle is less than 10A,
use a battery cable such as the RD-221 (sold separately) for the battery (yellow lead) and feed the
electricity directly from the battery.
• This unit is for vehicles with a 12-volt battery and
negative grounding. Before installing it in a recreational vehicle, truck, or bus, check the battery voltage.
• Speakers connected to this unit must be high-power
types with minimum rating of 60 W and impedance
of 4 to 8 ohms. Connecting speakers with output
and/or impedance values other than those noted
here may result in the speakers catching fire, emitting smoke or becoming damaged.
• Cords for this product and those for other products 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.

Installation <ENGLISH>
Note:
• Before finally installing the unit, connect the
wiring temporarily, making sure it is all connected
up properly, and the unit and the system work
properly.
• Use only the parts included with the unit to ensure
proper installation. The use of unauthorized parts
can cause malfunctions.
• Consult with your nearest dealer if installation
requires the drilling of holes or other modifications
of the vehicle.
• Install the unit where it does not get in the driver’s
way and cannot injure the passenger if there is a
sudden stop, like an emergency stop.
• The semiconductor laser will be damaged if it
overheats, so don’t install the unit anywhere hot —
for instance, near a heater outlet.
• If installation angle exceeds 60° from horizontal,
the unit might not give its optimum performance.
