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 car chassis.
Speakers
Connect the speaker wires. See the connection
diagram ( page 62) 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 45 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.
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
page
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 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.
Product
Connect any optional product such as an amplifier,
according to the instructions furnished with the
product. Leave 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 of any
product 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 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.
