Qldentify All Leads
The first step in instatlation is to identity ail the vehi-
cle 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 contusion 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 feads with electrical tape
until you are ready to use them. Identify the leads in
the following order.
Power Lead
If your vehicle has a radio or is pre-wired for one :
Cut the connector plug off (leaving the leads as long
as possible) so that you can work with individual
i=
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 al 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 vehicie
power lead.
if your vehicle is not wired for an audio unit :
Go to the fuse block and find the fuse port for radio
(RADIO), accessory (ACC), of ignition (IGN).
Battery Lead
It your stereo unit has a yellow lead, you will need
to locate the vehicle's battery lead. Otherwise you
may ignore this procedure, (The yellow battery lead
provides continuous power to maintain a clock,
memory storage, or ather function.)
If your vehicle has a radio or is pre-wired for one:
With the ignition and headlights off, identify the ve-
hicle battery lead by grounding one lead of the test
bulb to the chassis and checking the remaining ex-
Posed wires from the cut radio connector plug.
if your vehicle is not wired for an audio unit :
Go to the fuse biock and find the fuse port for the
battery, usually marked BAT.
Speakers
identify the vehicle speaker teads, There will be two
leads for each speaker, usually color coded.

Battery
Connect the yellow battery lead to the correct radio
wire orto 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 amplifier,
according to the instructions furnished with the
equipment. Keep about 12 inches (30 cm) of dis-
tance between the speaker cords/arplifier unit and
the antenna/antenna extension cord. Read the op-
erating and installation instructions for any equip-
ment you will connect to this unit.
Power
Connect the red power tead to the correct vehicle
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 pro-
ceed to the final installation,
Q Final Installation
Lead Connections
Connect all wires, making sure that each connec-
tion 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! Aiter making a few final checks,
you're ready to enjoy your new auto stereo system.
Q Final Checks
1. Make sure that all wires are properly connect-
ed 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 prop-
er cperation.
If you have difficulties, consult your nearest autho-
rized professional installer for assistance.
A handy way to identify the speaker Isads and the
speaker they connect with is to test the leads using
a 1.5 volt AA battery as follows.
Hold one tead against one pole of the battery and
'Stroke the other tead across the other pole. You will
hear a scraping sound in a speaker if you are hold-
ing a speaker lead.
if not, keep testing different {ead combinations until
you have jocated all the speaker leads. When you
label them, include the speaker location for each.
Antenna
The antenna lead is a thick, biack wire with a metal
Plug at the end.
Q Connect All Leads
Now that you have identified all the wires in the ve-
hicte, you're ready to begin connecting them to the
stereo unit wires. The connection diagram on Page
20 shows the proper connections and color coding
of the leads.
We strongly recommend that you test the unit be-
fore making a final installation,
You can set the unit on the floor and make tempo-
tary connections to test the unit. Use electrical tape
to cover all exposed wires.
ee
IMPORTANT : Connect the red power lead last,
after you have made and insulated ail other connec-
tions.
Ground
Connect the black ground lead of the power con-
nector to the metal vehicle chassis.
O Installation Procedures
1. Secure the Mounting Collar ©.
Speakers
Connect the speaker wires. See the wiring diagram
betow 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 35 watts {(CQ-2500CEU needs 22 watts) of
audio power. Speakers with low input ratings can
be damaged.
Speaker impedance should measure 4 - 8 ohms,
which is typically marked on most speakers. Lower
or higher impedance speakers will affect output and
can cause both speaker and sterao 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 insulat-
ed wires. If in doubt about how your vehicle's
speakers are wired, please consult with your near-
est professional installer.
