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
Page
23
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
vehicle chassis.
Speakers
Connect
the
speaker
wires.
See
the wiring
diagram on
Page 23
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
40
watts
of
audio power.
If
using
an
optional
audio
amplifier,
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
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
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.
