A handy way to identify the speaker leads and the

speaker they connect with is to test the leads using a

1.5 volt 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 hold­

ing 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 vehicle is equipped with an automatic power

antenna, identify the vehicle motor antenna lead by
connecting one bulb tester lead to the vehicle 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.

Telephone Mute (Only for CQ-R545EUC)

If you have a cellular phone, refer to its operator

manual to identify the telephone mute lead connec­

tion.

□ Connect All Leads

Now that you have identified all the wires in the vehi­

cle, you're ready to begin connecting them to the
stereo unit wires. The connection diagram on Pages
27, 28 show the proper connections and color cod­
ing 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 connec­

tor to the metal vehicle chassis.

Speakers
Connect the speaker wires. See the wiring diagram

below 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-R545/R525), 25watts (CQ-R520) 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 rat­

ings 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 stereo unit damage.

CAUTION

: Never ground the speaker cords. For ex­

ample, 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 car's speakers

are wired, please consult with your nearest profes­
sional installer.
