WX-850BT/900BT/900BTM
Ver. 1.1
(US and Canadian models)
Connection/Installation
Cautions
Run all ground (earth) leads to a common
ground (earth) point.
Do not get the leads trapped under a screw, or
caught in moving parts (e.g., seat railing).
Before making connections, turn the car ignition
off to avoid short circuits.
Connect the yellow and red power supply leads
only after all other leads have been connected.
Be sure to insulate any loose unconnected leads
with electrical tape for safety.
Precautions
Choose the installation location carefully so that
the unit will not interfere with normal driving
operations.
Avoid installing the unit in areas subject to dust,
dirt, excessive vibration, or high temperature,
such as in direct sunlight or near heater ducts.
Use only the supplied mounting hardware for a
safe and secure installation.
Note on the power supply lead (yellow)
When connecting this unit in combination with other
stereo components, the amperage rating of the car
circuit to which the unit is connected must be higher
than the sum of each component's fuse amperage
rating.
Mounting angle adjustment
Adjust the mounting angle to less than 45°.
Making connections
To a common ground (earth) point
First connect the black ground (earth) lead, then
connect the yellow and red power supply leads.
To the +12 V power terminal which is
energized at all times
Be sure to first connect the black ground (earth)
lead to a common ground (earth) point.
To the +12 V power terminal which is
energized when the ignition switch is set to
the accessory position
If there is no accessory position, connect to the
+12 V power (battery) terminal which is
energized at all times.
Be sure to first connect the black ground (earth)
lead to a common ground (earth) point.
To the power antenna (aerial) control lead or
the power supply lead of the antenna (aerial)
booster
It is not necessary to connect this lead if there is
no power antenna (aerial) or antenna (aerial)
booster, or with a manually-operated telescopic
antenna (aerial).
To AMP REMOTE IN of an optional power
amplifier
This connection is only for amplifiers and a
power antenna (aerial). Connecting any other
system may damage the unit.
To a car's illumination signal
Be sure to first connect the black ground (earth)
lead to a common ground (earth) point.

Subwoofer Easy Connection
You can use a subwoofer without a power amplifier
when it is connected to a rear speaker cord.
Note
Use a subwoofer with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to avoid
damage.
Memory hold connection
When the yellow power supply lead is connected,
power will always be supplied to the memory
circuit even when the ignition switch is turned off.
Speaker connection
Before connecting the speakers, turn the unit off.
Use speakers with an impedance of 4 to 8 ohms,
and with adequate power handling capacities to
avoid damage.
