Equipment
Connect any optional equipment such as an
amplifi er, according to the instructions furnished
with the equipment. Leave about 12
q (30 cm) of
distance between the speaker leads/amplifi er 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 fi nal 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 fi nal 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 diffi culties, consult your nearest
authorized professional installer for assistance.

Connect All Leads
Now that you have identifi ed all the wires in the
car, you are 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 fi nal installation.
You can set the unit on the fl oor 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 60 W (70 W ) of audio power.
If using an optional audio amplifi er, the speakers
should be able to handle the maximum amplifi er
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.
Motor Antenna
Connect the car motor antenna lead to the dark blue
motor antenna relay control lead.
(Do not confuse the antenna lead with blue/white
stripe lead for a power amplifi er.)
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.
Installation Guide

Identify All Leads
The fi rst 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 fi nd 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 fi nd the fuse port for radio
(RADIO), accessory (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 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 fi nd the fuse port for the
battery, 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
speaker 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 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.
