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

ɟ 

ˎ 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).

ˎ When your car has a built-in FM/AM antenna (aerial) in the 

rear/side glass, see “Notes on the control and power supply 
leads.”

This connection is only for amplifiers and a power antenna 
(aerial). Connecting any other system may damage the unit.

ɠ 

ˎ If there is no accessory position, connect to the +12 V power 

(battery) terminal which is energized at all times. 
Be sure to connect the black ground (earth) lead to a metal 
surface of the car first.

ˎ When your car has a built-in FM/AM antenna (aerial) in the 

rear/side glass, see “Notes on the control and power supply 
leads.”

ɡ 

Be sure to connect the black ground (earth) lead to a metal 
surface of the car first.

ˎ REM OUT lead (blue/white striped) supplies +12 V DC when you 

turn on the unit.

ˎ When your car has built-in FM/AM antenna (aerial) in the rear/

side glass, connect REM OUT lead (blue/white striped) or the 
accessory power supply lead (red) to the power terminal of the 
existing antenna (aerial) booster. For details, consult your dealer.

ˎ A power antenna (aerial) without a relay box cannot be used with 

this unit.

Memory hold connection
When the yellow power input 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 its damage.

ˎ Do not connect the speaker terminals to the car chassis, or 

connect the terminals of the right speakers with those of the left 
speaker.

ˎ Do not connect the ground (earth) lead of this unit to the 

negative (–) terminal of the speaker.

ˎ Do not attempt to connect the speakers in parallel.

ˎ Connect only passive speakers. Connecting active speakers (with 

built-in amplifiers) to the speaker terminals may damage the 
unit.

ˎ To avoid a malfunction, do not use the built-in speaker leads 

installed in your car if the unit shares a common negative (–) lead 
for the right and left speakers.

ˎ Do not connect the unit’s speaker leads to each other.

Be sure to install this unit in the dashboard of the 
car as the rear side of the unit becomes hot 
during use.

ˎ This unit is designed for negative ground (earth) 12 

V DC operation only.

ˎ Do not get the leads 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 input leads 

only after all other leads have been connected.

ˎ Run all ground (earth) leads to a common 

ˎ Be sure to insulate any loose unconnected leads 

with electrical tape for safety.

ˎ When connecting this unit in combination with 

other stereo components, the connected car 
circuit’s rating must be higher than the sum of 
each component’s fuse.

ˎ When no car circuits are rated high enough, 

connect the unit directly to the battery.

Subwoofer Easy Connection (ǵ-B)
You can use a subwoofer without a power amplifier 
when it is connected to a rear speaker cord.

* Do not connect a speaker in this connection.

ˎ Be sure to connect the ground (earth) lead before connecting the 

amplifier (ǵ-A).

ˎ The alarm will only sound if the built-in amplifier is used (ǵ-A).

ˎ Be sure to connect a 4 - 8 ohm subwoofer. Do not connect a 

speaker to the other rear speaker cord (ǵ-B).
