Connection diagram  
  To a metal surface of the car
First connect the black ground (earth) lead, then connect the  
yellow, and red power supply leads.
  To the power antenna (aerial) control lead or 
power supply lead of antenna (aerial) booster 
amplifier
Notes
  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).
  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.”
  To AMP REMOTE IN of an optional power 
amplifier
This connection is only for amplifiers. Connecting any other 
system may damage the unit.
  To the +12 V power terminal which is 
energized in the accessory position of the 
ignition key switch
Notes
  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.
  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.”
  To the +12 V power terminal which is 
energized at all times
Be sure to connect the black ground (earth) lead to a metal 
surface of the car first.
Notes on the control and power supply leads
  The power antenna (aerial) control lead (blue) supplies +12 V 
DC when you turn on the tuner.
  When your car has built-in FM/AM antenna (aerial) in the rear/
side glass, connect the power antenna (aerial) control lead 
(blue) or the accessory power supply lead (red) to the power 
terminal of the existing antenna (aerial) booster. For details, 
consult your dealer.
  A power antenna (aerial) without a relay box cannot be used 
with this unit.
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.
Notes on speaker connection
  Before connecting the speakers, turn the unit off.
  Use speakers with an impedance of 4 to 8 ohms, and with 
adequate power handling capacities to avoid its damage.
  Do not connect the speaker terminals to the car chassis, or 
connect the terminals of the right speakers with those of the 
left speaker.
  Do not connect the ground (earth) lead of this unit to the 
negative (–) terminal of the speaker.
  Do not attempt to connect the speakers in parallel.
  Connect only passive speakers. Connecting active speakers 
(with built-in amplifiers) to the speaker terminals may damage 
the unit.
  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.
  Do not connect the unit’s speaker leads to each other.
Note on connection
If speaker and amplifier are not connected correctly, “FAILURE” 
appears in the display. In this case, make sure the speaker and 
amplifier are connected correctly.
