This
application
is
used
when
you
want
to
maintain
the
stereo
effect
while
doubling
the
output
power
of
your
amplifiers.
The
right
amplifiers
are
connected
to
the
RIGHT
output
of
the
400
BDG
Bridging
Module
and
the
left
amplifiers
are
connected
to
the
LEFT
output.
In
this
system,
the
400
BDG
Bridging
Module
accepts
the
stereo
inputs
and
turns
one
channel
over
180
degrees
(inverts
the
channel).
Both
channel
outputs
of
each
amplifier
are
now
connected
to
the
speaker
with
the
inverted
channel
being
used
as
the
negative
input.
This
works
because
the
two
chan¬
nels
are
180
degrees
out-of-phase.
The
ORANGE
lead
from
each
amplifier
is
used
as
the
positive
lead
and
the
YELLOW
lead
is
used
as
the
negative
lead.
The
BLACK/YELLOW
and
BLACK/ORANGE
leads
are
not
used.
A
REMINDER:
The
speakers
must
never
be
grounded
to
the
car
chassis
or
body.
To
do
so
will
cause
severe
noise
problems
and,
in
the
case
of
bridging,
cancel
out
the
two-phase
operation.
