Preparing
the
hookup
wire
1.
Strip
off
3/8"
of
insulation
from
both
ends
of
each
conductor.
2.
Twist
each
set
of
thin
wires
into
a
tightly-bunched
spiral.
3.
At
this
point
you
need
to
identity
a
visual
difference
between
the
two
conductors
of
each
molded
pair
of
speaker
wire.
Differentiating
marks
can
be
a
different
color
wire
(copper
or
"silver");
a
strand
of
yarn
in
one
conductor;
thin,
raised
ribs
on
one
part
of
the
outer
insulation;
or
a
printed
"+"
marking
on
one
of
the
insulators.
It
does
not
make
a
difference
which
of
the
two
conductors
of
wire
go
to
(+)
and
(-)
on
the
speakers
and
amplifier,
as
long
as
both
speakers
are
connected
identically.
However,
in
order
to
maintain
polarity
between
all
of
the
speakers
in
the
system,
you
should
adhere
to
the
same
(+)
and
(-)
designation
method
for
all
speakers.
Push
down
on
the
button
below
the
terminal
and
insert
the
wire
through
the
hole
de
ia

2)
Insert

Push
te
wire

A
(3)
Release
For
each
channel,
the
red
terminal
on
the
loudspeaker
should
be
connected
to
the
red
or
(+)
loudspeaker
connection
terminal
on
the
receiver
or
amplifier,
and
the
black
to
the
black
or
(-).
Connecting
the
loudspeakers
in
this
manner
ensures
that
they
will
be
in
phase;
that
is,
work
together
rather
than
in
opposition.
Connecting
the
loudspeakers
out
of
ohase
will
not
damage
them,
but
will
result
in
less
bass
and
poor
imaging.
TROUBLESHOOTING
The
vast
majority
of
new
speaker
"malfunctions"
end
up
being
traced
to
connections
or
switch
settings.
To
avoid
packing
up
correctly
functioning
speakers
and
sending
them
off,
only
to
find
that
they're
not
really
at
fault,
check
the
following
tips
first,
before
requesting
service.
No sound
from
one
speaker
1.
Balance
control
turned
all
the
way
left
or
right.
2.
Speaker
wire
has
become
disconnected.
3.
One
of
the
connections
between
sound
source
and
amplifier
is
faulty
or
has
become
disconnected.
.
Both
speakers
play
at
low
volumes
but
shut
off
as
volume
is
increased
OR
sound
turns
on
and
off
intermittently
A
few
strands
of
speaker
wire
may
be
shorting
out.
Recheck
the
connections.
Recheck
the
impedance
requirements
of
the
amp.
Bass
is
very
weak
AND/OR
sound
seems
to
come
from,
instead
of
between
the
speakers
|
1.
The
polarity
(+&-)
of
one
speaker
has
been
reversed
relative
to
the
other.
Double
check
connections.
2.
Speakers
are
too
far
away
from
back
and
side
walls
of
car.
Experiment
again
with
the
speaker
placement.
If
you
are
still
experiencing
problems,
consult
your
JBL
dealer.
