Connect All Leads
Now that you have identified all the wires in the
car, you’re ready to begin connecting them to
the stereo unit wires. The wiring diagram (
➡
page 70) shows 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 car chassis.
Speakers
Connect the speaker wires. See the wiring
diagram (
➡
page 70) 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 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 blue
motor antenna relay control lead.

Cautions:
≥
Continuous use of this unit will cause the power amplifier unit to become hot. Be careful not to touch
the power amplifier unit while it is in operation. Also, do not place other objects on top of the power
amplifier unit.
≥
Do not install the power amplifier unit in a location where it may be subject to damage from
overheating, such as next to a heater vent, or in a location exposed to direct sunlight such as the
dashboard or the rear window deck.
≥
Do not install the power amplifier unit near a door or other locations where it may be readily exposed
to water or stepped on.
≥
Clean away all oil, moisture, dust, etc., from the surface where the velcro tape is to be applied.
≥
When drilling holes in the car, make certain that you do not damage any pipes or wiring on the
underside of the car.
≥
When installing the power amplifier unit, make sure that the cord is positioned in a location where it
will not be pinched or damaged when the seat slides forward or backward.
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 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
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.
