DSX-GS900
This section is extracted from
operating instruction.
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.
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.
Note on installing in cars with a start-stop system
The unit may restart when starting the engine from
start-stop. In this case, turn off the start-stop system of
your car.
Mounting angle adjustment
Adjust the mounting angle to less than 30°.
*1 Not supplied
*2 Speaker impedance: 4 Ω to 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 14).
*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.
For details on installing the microphone, see
.
"Installing the microphone" (page 13).
*6 Depending on the type of car, use an adaptor (not
supplied) if the antenna (aerial) connector does not
fit.
*7 For more information on how to install the SiriusXM
Connect Vehicle tuner, consult the installation guide
included with the tuner.
*8 To connect a smartphone to the main unit, an
appropriate cable (not supplied) is required.
*9 To connect an iPod/iPhone, use the USB connection
cable for iPod (not supplied).
*10 Ferrite sleeve
*11 Use speakers with 50W RMS or higher power input
capacity. Using Sony XB series full range speakers is
recommended.
*12 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.
*13 Before connection, arranging the yellow and black
leads of the power supply leads
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.

SECTION 2
Connection
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
is required.
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.
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 2 mm² ( 3 / in).

When making the speaker parallel connection, use wires
with more than 12-Gauge (AWG12) or wires that have a
sectional area of more than 3.5 mm² ( 5 /

If you have any questions or problems concerning
the connection, consult the dealer for details.
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 a 2 Ω impedance or 4 Ω to 8 Ω
impedance, and with adequate power handling
capacities to avoid damage.
