□ Connect All Leads
Now that you have identified all the wires in the
vehicle, you're ready to begin connecting them to
the stereo unit wires. The connection diagram on
Pages 52 to 53 show the proper connections and
color coding of the leads.
We strongly recommend that you test the unit
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 vehicle chassis.
Speakers
Connect the speaker wires. See the wiring
diagram for the proper hookups. Follow the
diagram carefully to avoid damaging the speakers
and the stereo unit.
The speaker used must be able to handle more
than 40 W of audio power. If using an optional
audio power, 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 n,
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 in doubt about how your
car's speakers are wired, please consult with your
nearest professional installer.
Motor Antenna
Connect the vehicle motor antenna lead to the
blue motor antenna relay control lead.
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 amplifier,
according to the instructions furnished with the
equipment. Keep about 12 inches (30 cm) of
distance between the speaker cords/amplifier unit
and the antenna/antenna extension cord. Read
the operating and installation instructions for any
equipment you will connect to this unit.
Power
Connect the red power lead to the correct vehicle
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
won't 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 con­
nected 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.
