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.

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.

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.

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 56) 
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 56) 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 50 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.

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.
