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.
Precautions
• 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.
Mounting angle adjustment
Adjust the mounting angle to less than 45°.
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.
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
