Owner's Manual
Installation
Information
Memphis
Audio
recommends
the
installation
of
our
products
to
be
performed
by
an
Authorized
dealer.
Attempting
an
installation
project
on
your
own
or
through
an
unauthorized
source
may
result
in
damage
to
your
products
and
may
potentially
void
your
warranty.
Amplifiers
should
be
mounted
in
areas
that
receive
adequate
ventilation.
These
amplifiers
are
water
and
element
resistant
but
should
be
mounted
in
areas
that
do
not
receive
excessive
direct
contact
with
water.
These
amplifiers
are
not
intended
to
be
submerged
and
care
should
be
used
when
determining
a
mounting
location.
Warning
For
your
safety,
always
inspect
the
mounting
location
carefully
to
ensure
you
are
not
drilling
into
any
electrical,
hydraulic,
fuel
or
fluid
lines.
Always
check
your
speaker
load
with
a
multi-meter
before
connecting
the
amplifier.
Connecting
any
speaker
load
lower
than
the
rated
impedance
of
the
amplifier
will
result
in
damage
to
the
amplifier.
Damage
of
this
nature
is
NOT
covered
under
warranty.
Please
pay
close
attention
to
what
connections
are
made
to
the
amplifier.
Troubleshooting
When
troubleshooting
your
amp,
speaker
and
speaker
wires
should
be
tested
first.
No
Output:
·Confirm
all
wiring
is
firmly
connected.
Both
+12V
and
REM
terminals
must
have
+12
Volts
present
and
GND
must
be
connected
to
chassis'
ground
or
to
the
negative
battery
terminal.
·Confirm
the
signal
source
is
connected
and
supplying
an
output
signal.
To
confirm
the
amp
is
working,
connect
an
RCA
patch
cord
to
the
line
inputs
of
the
amplifier
[do
not
connect
the
other
end
of
the
patch
cord).
Briefly
tap
the
center
pin
of
each
disconnected
RCA
with
your
finger.
This
should
produce
a
noise
[brief
static
or
hum)
in
the
speakers.
The
Amp
Is
Hot:
check
the
speaker
impedance
or
load.
The
total
minimum
impedance
of
all
speakers
should
not
be
lower
than
the
rating
of
the
amp.
Only
One
Channel
Works:
•
Confirm
the
speaker
terminal
strip
connections
are
firmly
connected.
•
Check
"balance"
control
on
your
signal
source.
•
If
using
RCA
Low-Level
inputs,
reverse
the
input
plugs
at
the
amplifier.
If
the
channel
that
is
silent
reverses
position,
the
problem
is
in
the
source
unit
or
connecting
cable.
Weak
Output
•
Check
input
sensitivity
control
adjustment.
Unwanted
Noise
·Whine
that
increases
and
decreases
with
engine
speed
-
confirm
the
Amp
6
Source
unit
are
grounded
properly.
·Clicking
or
popping
noise
at
a
rate
that
follows
engine
speed-
this
is
often
induced
by
the
vehicles
ignition
system.
Confirm
that
the
vehicle
is
equipped
with
resistor
spark
plugs
and
wires.
The
ignition
system
may
need
service.
•
Noise
can
be
caused
by
routing
speaker
input
wires
too
close
to
the
light
wires
and
other
accessory
wires
in
the
vehicle.
Re-route
wires
to
avoid
unwanted
interference.
·If
above
steps
do
not
improve/reduce
noise,
the
system
should
be
checked
by
a
professional
audio
installer
at
a
Memphis
Authorized
Dealer.
