ˎ Run all ground (earth) leads to a common 

ˎ Do not get the leads trapped under a screw, or 

caught in moving parts (e.g., seat railing).

ˎ Before making connections, turn the car ignition 

off to avoid short circuits.

ˎ Connect the yellow and red power supply leads 

only after all other leads have been connected.
For Argentine models: Connect the power supply 
lead 

ʙ to the unit and speakers before 

connecting it to the auxiliary power connector.

ˎ Be sure to insulate any loose unconnected leads 

with electrical tape for safety.

ˎ Choose the installation location carefully so that 

the unit will not interfere with normal driving 
operations.

ˎ Avoid installing the unit in areas subject to dust, 

dirt, excessive vibration, or high temperature, 
such as in direct sunlight or near heater ducts.

ˎ 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.

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).

*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 AUDIO OUT can be switched to SUB or REAR.
*7 Note for the antenna (aerial) connecting (Argentine 

models only): 

If your car antenna (aerial) is an ISO (International 
Organization for Standardization) type, use the 

supplied adaptor 

ͭ to connect it.

ɞ To a common ground (earth) point

First connect the black ground (earth) lead, then 
connect the yellow and red power supply leads.

ɟ 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.

ɠ 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.

If you have a power antenna (aerial) without a relay 
box, connecting this unit with the supplied power 
supply lead 

ͬ may damage the antenna (aerial).

You can use a subwoofer without a power amplifier 
when it is connected to a rear speaker cord.

ˎ Preparation of the rear speaker cords is required 

(Argentine models only).

ˎ Use a subwoofer with an impedance of 4 to 8 ohms, 

and with adequate power handling capacities to 

avoid damage.

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.

ˎ Before connecting the speakers, turn the unit off.

ˎ Use speakers with an impedance of 4 to 8 ohms, 

and with adequate power handling capacities to 
avoid damage.

When replacing the fuse, be sure 
to use one matching the 
amperage rating stated on the 
original fuse. If the fuse blows, 
check the power connection and 
replace the fuse. If the fuse blows 
again after replacement, there 
may be an internal malfunction. In such a case, 
consult your nearest Sony dealer.
