Installation Guide
Connect All Leads
E Now that you have identified all the wires in the car,
N
you're ready to begin connecting them to the stereo
G
unit wires. The wiring diagram ( page 68) shows
L
I
the proper connections and color coding of the
S
leads.
H
We strongly recommend that you test the unit
49
before making a final installation.
You can set the unit on the floor and make
temporary connections to test the unit. Use
electrical tape to cover all exposed wires.
Important:
Connect the red power lead last, after you have
≥
made and insulated all other connections.
Ground
Connect the black ground lead of the power
connector to the metal car chassis.
Speakers
Connect the speaker wires. See the wiring diagram
( page 68) for the proper hookups. Follow the
diagram carefully to avoid damaging the speakers
and the stereo unit.
The speakers used must be able to handle more
than 50 W of audio power. If using an optional
audio amplifier, the speakers should be able to
handle the maximum amplifier output power.
Speakers with low input ratings can be damaged.
Speaker impedance should measure 4–8 ≠, which
is typically marked on most speakers. Lower or
higher impedance speakers will affect output and
can cause both speaker and stereo unit damage.
Caution:
Never ground the speaker cords. For example,
≥
do not use a chassis ground system or a three-
wire speaker common system. Each speaker
must be connected separately using parallel
insulated wires. If you are in doubt about how
your car's speakers are wired, please consult
your nearest professional installer.
Motor Antenna
Connect the car motor antenna lead to the dark blue
motor antenna relay control lead.
(Do not confuse the antenna lead with blue/white
stripe lead for a power amplifier. )

Battery
Connect the yellow battery lead to the correct radio
wire or to the battery fuse port on the fuse block.
Antenna
Connect the antenna by plugging the antenna lead
into the antenna receptacle.
Equipment
Connect any optional equipment such as an
amplifier, according to the instructions furnished
with the equipment. Leave about 12z (30 cm) of
distance between the speaker leads/amplifier unit
and the antenna/antenna extension cord. Read the
operating and installation instructions of any
equipment you will connect to this unit.
Power
Connect the red power lead to the correct car radio
wire or to the appropriate fuse port on the fuse
block.
If the stereo unit functions properly with all these
connections made, disconnect the wires and
proceed to the final installation.
Final Installation
Lead Connections
Connect all wires, making sure that each
connection is insulated and secure. Bundle all loose
wires and fasten them with tape so they will not fall
down later. Now insert the stereo unit into the
mounting collar.
Congratulations! After making a few final checks,
you're ready to enjoy your new auto stereo system.
Final Checks
1. Make sure that all wires are properly connected
and insulated.
2. Make sure that the stereo unit is securely held
in the mounting collar.
3. Turn on the ignition to check the unit for proper
operation.
If you have difficulties, consult your nearest
authorized professional installer for assistance.
Preparation
≥ We strongly recommend that you wear gloves
for installation work to protect yourself from
injuries.
≥ When bending the mounting tabs of the
mounting collar with a screwdriver, be careful
not to injure your hands and fingers.
≥ Disconnect the cable from the negative - battery
terminal (see cautions below).
≥ Unit should be installed in a horizontal position
with the front end up at a convenient angle, but
less than 30o.
Less than 30x
Caution:
≥ Do not disconnect the battery terminals of a car
with a trip or navigational computer since all
user settings stored in memory will be lost.
Instead take extra care with installing the unit
to prevent shorts.
