RCA
Analog
Line-Level
Inputs
-The
line-level
outputs from
the
head
unit
or factory
installed radios can connect here,
so
the
ACM-4.300 will
receive the line-level
audio
signals.
Do
not
use
the
speaker-level
inputs
if
you are using
the
RCA
line-level
inputs.
7.
Speaker-Level
Output Terminals
-These
screw
terminals
connect
with
speaker wire
to
your
loudspeakers. Make sure
that
the average combined speaker impedance does
not
dip
below
2
Ohms
per channel.
Make sure
that
you
follow
the
plus
and
minus
polarity
markings on the
ACM-4.300
and match
it
to
the
polarity
of
your
loudspeakers.
In
Stereo operation ,
connect one
loudspeaker
to
each
channel
as
shown. The
minimum
impedance
is
2
Ohms
per
channel.
In
Bridged Mono operation ,
connect one
loudspeaker
to
the in-
ner 2 screw
terminals
(Channell+
and Channel
2-)
as
shown. The
mono
loudspeaker will receive the power from each
channel,
and
both
channel inputs must be fed
an
input
signal. The
minimum
impedance
is
4 Ohms. Connect stereo speakers
to
channels 3 and
4
as
shown, or another
Mono
speaker.
