Identify All Leads
H
The first step in installation is to identify all the car wires
14
you'll use when hooking up your sound system.
As you identify each wire, we suggest that you label it
using masking tape and a permanent marker. This will
help avoid confusion when making connections later.
Note: Do not connect the power connector to the stereo
unit until you have made all connections. If there are no
plastic caps on the stereo hooking wires, insulate all
exposed leads with electrical tape until you are ready to
use them. Identify the leads in the following order.
Power Lead
If your car has a radio or is pre-wired for one:
Cut the connector wires one at a time from the plug
(leaving the leads as long as possible) so that you can
work with individual leads.
Turn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis.
Touch the other lead of the test bulb to each of the
exposed wires from the cut radio connector plug. Touch
one wire at a time until you find the outlet that causes
the test bulb to light.
Now turn the ignition off and then on. If the bulb also
turns off and on, that outlet is the car power lead.
If your car is not wired for an audio unit: Go to the fuse
block and find the fuse port for radio (RADIO), accesso-
ry (ACC), or ignition (IGN).
Battery Lead
If your stereo unit has a yellow lead, you will need to
locate the car's battery lead. Otherwise you may ignore
this procedure. (The yellow battery lead provides contin-
uous power to maintain a clock, memory storage, or
other function.)
If your car has a radio or is pre-wired for one:
With the ignition and headlights off, identify the car bat-
tery lead by grounding one lead of the test bulb to the
chassis and checking the remaining exposed wires from
the cut radio connector plug.

If your car is not wired for an audio unit:
Go to the fuse block and find the fuse port for the bat-
tery, usually marked BAT.
Speakers
Identify the car speaker leads. There are two leads for
each speaker which are usually color coded.
A handy way to identify the speaker leads and the speak-
er they are connected with is to test the leads using a
1.5 V AA battery as follows.
Hold one lead against one pole of the battery and stroke
the other lead across the other pole. You will hear a
scraping sound in one of the speakers if you are holding
a speaker lead.
If not, keep testing different lead combinations until you
have located all the speaker leads. When you label them,
include the speaker location for each.
Antenna
The antenna lead is a thick, black wire with a metal plug
at the end.
Connect All Leads
Now that you have identified all the wires in the car, you
are ready to begin connecting them to the stereo unit
wires. The wiring diagram ( page 25) shows the prop-
er 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 25) 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 Ω, 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 an amplifier,
according to the instructions furnished with the equip-
ment. Leave about 12" (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 con-
nections 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 author-
ized 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 ter-
minal (see cautions below).
• Unit should be installed in a horizontal position with
the front end up at a convenient angle, but not more
than 30˚.
Less than 30˚
Caution: Do not disconnect the battery terminals of
a car with a trip or navigational computer since all
user settings stored in memorywill be lost. Instead
take extra care with installing the unit to prevent
shorts.
