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 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
batter y 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
on Page 30 show 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 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 40 watts 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.
