SAFE
LIMITS
OF
OPERATION
Polk
Audio
specifies
the
recommended
amplification
range
for
each
of
its
passive
(non-amplified)
loudspeakers.
Typi-
cally
that
specification
will
be
expressed
as
a
range
of
power
such
as
20-200
Watts
(per
channel).
It
is
important
to
understand
what
those
numbers
mean
when
choosing
a
receiver
or
amplifier
for
your
Polk
loudspeakers.
The
lower
number
indicates
the
lowest
continuous
rated
power
that
will
yield
acceptable
performance
in
a
typical
listening
environment.
The
higher
number
indicates
the
highest
per
channel
power
that
should
be
used
with
your
Polk
speakers.
That
number
should
not
be
confused
with
a
"Power
Handling"
specification
and
it
does
not
imply
that
the
speaker
will
safely
handle
that
full
amount
of
power
on
a
long-term
basis.
We
specify
a
wide
range
of
power
ratings
because
not
all
electronics
manufacturers
use
the
same
method
for
rating
power.
In
fact,
high
quality
lower-
rated
amplifiers
sound
better
and
play
louder
than
low
quality
units
with
higher
power
rating.
Automobile
horsepower
is
good
analogy.
Your
car
probably
has
far
more
horsepower
than
it
needs
for
your
daily
com-
mute
and
is
likely
capable
of
going
well
over
120
MPH
(190KM/hr).
Having
that
extra
power
is
good
for
on-ramp
acceleration
and
danger
avoidance
(like
getting
away
from
brain-eating
zombies)
but
that
doesn't
mean
that
it
is
advis-
able
to
operate
your
car
on
North
American
highways
at
full
power
and
maximum
speed
for
an
extended
period
of
time.
Just
ask
your
local
state
trooper
if
you
are
in
doubt.
Similarly,
we
recommend
using
amplifiers
and
receivers
with
rated
power
above
the
Power
Handling
limits
of
our
speakers
because
having
extra
power
available
for
short
terms
peaks
is
conducive
to
better
sound
quality,
maximum
dynamic
range
and
effortless
high
volume
output.
But
we
strongly
urge
you
not
to
use
the
full
power
of
your
amp
or
receiver
for
daily
listening.
Loudspeakers
can
be
damaged
when
an
amplifier,
regard-
less
of
its
wattage,
is
made
to
play
at
higher
listening
levels
than
its
power
can
clearly
produce.
Operation
at
this
level
can
result
in
very
high
levels
of
audible
distortion
originating
in
the
amplifier,
which
can
add
a
harsh,
gritty
sound
to
your
ENGLISH
listening
material.
If
you
hear
distortion-turn
the
vol-
ume
down
or
risk
damaging
your
speakers.
You
can
damage
just
about
any
speaker,
regardless
of
power
rating,
if
you
drive
an
amplifier
to
or
beyond
the
point
of
distortion.
INSTALLATION
GUIDELINES
1.
Please
read
this
owner's
manual
carefully
before
installing
this
amplifier.
2.
Disconnect
the
battery
ground
terminal
prior
to
making
any
electrical
connections.
3.
Check
for
any
hazards
or
obstructions
such
as
gas
tanks,
fuel
or
brake
lines,
and
wiring
harnesses
before
mounting
the
amplifier.
4.
Pick
a
mounting
location
that
will
provide
adequate
access
and
ventilation
and
protect
the
amplifier
from
heat,
moisture,
and
dirt.
5.
To
securely
mount
your
amplifier
you
must
first
remove
the
top
cover
assembly.
Unscrew
the
four
(4)
top
cover
assembly
retaining
screws
using
the
supplied
4mm
Allen
Wrench.
6.
Avoid
sharp
metal
areas
when
routing
cables
to
the
amplifier,
and
run
RCA
cables
away
from
the
power
cables
and
other
potentially
noisy
car
harnesses.
7.
The
amplifier
should
be
grounded
with
a
short,
heavy
gauge
wire
connected
directly
to
the
car
at
a
bare
metal
surface,
preferably
scraped
body
sheet
metal.
Do
not
use
factory
ground
locations,
seat
bolts,
or
brackets
that
are
spot
welded.
8.
Always
fuse
your
power
connection
within
8
to
10
inches
of
the
battery
terminal.
Use
a
fuse
or
circuit
breaker
rated
slightly
more
than
the
on-board
fuse(s)
of
the
amplifier(s).
The
gauge
of
power
wire
used
should
take
into
account
the
total
current
draw
of
the
system,
and
the
length
of
wire
used.
IASCA
and
other
auto
sound
competition
organizations
have
charts
available
for
this;
you
can
also
find
a
chart
in
the
MECP
study
guide.
Minimum
wire
gauge
recommendations
for
the
individual
ampli-
fiers
are
listed
on
the
specification
page.
Always
use
the
same
gauge
wire
for
the
amplifier
ground
that
you
use
for
the
power
wire.
Be
sure
to
examine
the
battery
ground
cable
of
the
vehicle,
and
if
necessary,
upgrade
it
by
adding
an
additional
ground
wire
that
is
the
same
gauge
as
the
amplifier's
power
wire.
Remember,
the
amplifier
can
only
deliver
its
rated
output
when
it
is
not
current
limited
by
the
power
and
ground
supply
wires.
9.
This
amplifier
is
designed
to
drive
a
speaker
load
that
measures
from
1
to
4
Ohms.
Keep
in
mind
that
heat
is
the
long-term
enemy
of
automotive
electronics
and
the
lower
your
speaker
load,
the
more
heat
is
generated.
For
low-impedance
speaker
applications
or
restricted
ventilation
installations,
an
external
cooling
fan
may
be
advisable.
