Cautions

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.

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°.

Connection/Installation

Precautions

Installation

Before installing the unit, remove the protection 
collar ͨ and the bracket ʓ from the unit.

1

Pinch both edges of the protection collar 

ͨ, then pull it out.

2

Insert both release keys ͧ until they 
click, and pull down the bracket ʓ, then 
pull up the unit to separate.

†

ͧ

Face the hook inwards.

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.

ɡ 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.

Making connections

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

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.
