Memphis Power Reference Series - Wiring Multi-Channel Amplifiers

Wiring
Multi-Channel
Amps
Speaker
have
a
positive
and
negative
marking
on
the
terminals.
These
are
used
to
indicate
polarity
and
must
be
considered
when
wiring
speakers
or
subwoofers
to
an
amplifier.
Amplifiers
also
have
positive
and
negative
markings
on
their
speaker
outputs.
Use
these
marking
to
match
polarities
to
ensure
the
speakers
are
in
phase.
Failure
to
wire
speakers
or
woofers
in
phase
with
one
another
will
result
in
a
loss
of
bass.
All
street
reference
amplifiers
require
a
minimum
2ohm
impedance
in
stereo
or
q
ohms
in
mono
(bridged)
mode.
A
Always
check
your
speaker
load
with
a
multi-meter
before
hooking
them
up
to
the
amplifier.
The
PRXA300.LI/PRXA300.2
amplifier
is
stable
to
2
ohms
stereo
or
Q
ohms
bridged
mono.
The
PRXA700.5
amplifiers
are
stable
to
2
ohms
stereo
or
Q
ohms
bridged
mono
[frontS
rear
channels]
and
stable
to
2
ohms
(sub
channel].
Any
Impedance
(load]
smaller
than
what
is
recommended
will
damage
the
amplifier!
Such
damage
is
not
covered
under
warranty,
so
pay
strict
attention
to
what
connections
are
made
to
the
amplifier.
