Connecting the Units
Fig. 2
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 insu-
lation 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 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 the RCA pin jack on the unit will not be used,
do not remove the caps attached to the end of the
connector.
• Speakers connected to this unit must be high-
power types with minimum rating of 50 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 catch-
ing 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 anten-
na 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 ter-
minal 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 pos-
sibility of short-circuiting if the leads are not insu-
lated.
• 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 col-
ors 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 connect-
ed to a terminal coupled with ignition switch
ON/OFF operations. If this is not done, the vehi-
cle battery may be drained when you are away
from the vehicle for several hours. (Fig. 1)
Fig. 1
• 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 dam-
age to the products or fire.

• 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
Installation manuals of both products and
connect cords that have the same function.
Installation
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 modifica-
tions 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 30° from horizontal,
the unit might not give its optimum performance.

Installation using the screw holes on the side of the unit
Fastening the unit to the factory radio mounting bracket. (Fig. 4) (Fig. 5)
Select a position where the screw holes of the bracket and
the screw holes of the head unit become aligned (are fit-
ted), and tighten the screws at 3 or 4 places on each side.
Use either binding screws (5
× 8 mm) or flush surface
screws (5
× 8 mm), depending on the shape of the screw
holes in the bracket
.

Note:
When a subwoofer is connected to this unit instead of a rear speaker,
change the rear output setting in the Initial Setting (refer to the
Operation Manual). The subwoofer output of this unit is monaural.
