lnstallation
Guide
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.
lf not, keep
testing
different lead combinations
until
you
have
located
allthe speaker leads. When
you
label
them, include
the
speaker location for
each.
Antenna
Motor
lf
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
lf
you
have
a cellular
phone,
refer
to its
operator
manual
to identify
the
telephone mute
lead
con-
nection.
o
Connect
All Leads
Now
that
you
have identified
all the
wires in the
vehicle,
you're
ready
to begin
connecting them
to
the
stereo
unit wires. The
connection
diagram on
Pages
41 and
42 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 tempo-
rary
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 con-
nections.
Ground
Connect the
black
ground
lead
of the
power
con-
nector
to the metal
vehicle
chassis.
continued
Speakers
Connect
the
speaker wires.
See the wiring
dia-
gram
below 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
the
maximum
amplifier output
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 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
speak-
er must
be connected
separately using
parallel
insulated wires.
lf in
doubt about how
your
car's
speakers
are wired,
please
consult with
your
near-
est
professional
installer.
