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°.
*1 Not supplied
*2 Speaker impedance: 4 – 8 Ω × 4
*3 RCA pin cord (not supplied)
*4 Depending on the type of car, use an adaptor for a
wired remote control (not supplied).
For details on using the wired remote control, see
"Using the wired remote control" (page 32). "
*5 Whether in use or not, route the microphone input
cord such that it does not interfere with driving
operations. Secure the cord with a clamp, etc., if it is
installed around your feet.
*6 For details on installing the microphone, see
"Installing the microphone" (page 32). "
*7 Use speakers with 50W RMS or higher power input
capacity. Using Sony XB series full range speakers is
recommended.
*8 When the amperage rating of the fuse used on your
car is 10 A, make the power connection to the
battery directly to avoid short circuits.
Making connections
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.
To a common ground (earth) point
First connect the black ground (earth) lead, then
connect the yellow and red power supply leads.
Connection
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.
When connecting to the battery directly
When the amperage rating of the fuse used on your
car is 10 A, make the power connection to the
battery directly to avoid short circuits.
to a metal point of car
to the positive battery terminal
Notes
Despite connecting to the power supply lead of the
car, the unit may not fully provide its performance
due to insufficient power. In this case, make the
power connection to the battery directly.
All power wires connected to the positive battery post
should be fused within 450 mm (18 in) of the battery
post, and before they pass through any metal.
Make sure that the car's battery wires connected to
the car (ground (earth) to chassis)* are of a wire
gauge at least equal to that of the main power wire
connected from the battery to the head unit.
During full-power operation, a current of more than
15 A will run through the system. Therefore, make
sure that the wires to be connected to the +12 V and
GND terminals of this unit are at least 14-Gauge
(AWG14) or have a sectional area of more than 2mm²
( 3 / in).

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.
