□ 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
Page 23 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 on Page 23 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 40 watts 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 ohms,
which is typically marked on most speakers.
Lower or higher impedance speakers will affect
output and can cause both speaker and stereo
unit damage.
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.
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.
□ 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.
