❏ Dashboard Specifications

❏ Identify All Leads

The first step in installation is to identify all the car
wires 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), accessory (ACC), or ignition (IGN).

Thickness
Min. 3/16" (4.75 mm)
Max. 7/32" (5.56 mm)

7-5/32" (182 mm)

2-3/32" (53 mm)

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 continuous 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
battery 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
battery, usually marked BAT.

Speakers

Identify the car speaker leads. There will be two
leads for each speaker, usually color coded.
A handy way to identify the speaker leads and the
speaker they connect 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 a speaker 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 Motor

If your car is equipped with an automatic power
antenna, identify the car motor antenna lead by con­necting one bulb tester lead to the car battery lead
and touching the remaining exposed wires from the
cut radio connector plug one at a time. You will hear
the antenna motor activate when you touch the cor­rect wire.

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're ready to begin connecting them to the stereo
unit wires. The connection diagram (B Page 40)
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
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
45 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 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.

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 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.

Equipment

Connect any optional equipment such as an amplifi­er, according to the instructions furnished with the
equipment. 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 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
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.

❏ Precautions

Installation Guide (continued)

¡We strongly recommend that you wear gloves

for installation work to protect yourself from
injuries.

¡When bending the mounting tab of the mount-

ing collar with a screwdriver, be careful not to
injure your hands and fingers.

Caution: Do not disconnect the battery terminals
of a car with trip or navigational computer since
all user settings stored in memory will be lost.
Instead take extra care with installing the unit to
prevent shorts.

¡Disconnect the cable from the negative (

-

) battery

terminal (see caution below).

¡Unit should be installed in a horizontal position

with the front end up at a convenient angle, but
