Appropriate
mounting
is
very
important
for
the
prolonged
life
expectancy
of
any
amplifier.
Select
a
location
that
allows
enough
space
so
sufficient
airflow
is
maintainable
and
a
location
that
provides
protection
from
moisture.
Keep
in
mind
that
an
amplifier
should
never
be
mounted
upside
down.
Upside
down
mounting
will
compromise
heat
dissipation
through
the
heatsink
and
could
engage
the
thermal
protection
circuit.
Excessive
heat
will
shorten
your
amplifiers
life.
To
maximise
heat
dissipation,
be
sure
to
leave
at
least
2.5"
of
clearance
around
the
amplifier.
If
space
is
of
the
essense
and
the
amplifier
must
be
mounted
in
an
enclosed
or
restricted
area,
a
small
3
inch
fan
should
be
used
in
correspondence
with
a
duct
so
the
heat
can
flow
past
the
FUTRANZ
Heatsink.
Try
to
avoid
mounting
any
amplifier
on
a
subwoofer
enclosure,
as
extended
exposure
to
vibration
may
cause
malfunction
of
the
amplifier.
To
avoid
scratching
your
new
FUSION
amplifier,
pre·drill
the
mounting
holes
with
either
a
3mm
or
g/64"
diameter
drill
bit
and
use
the
screws
supplied
in
the
accessory
kit.
Be
sure
to
investigate
your
mounting
area
thoroughly
to
avoid
electrical
wires,
vacuum
lines
and
fuel
lines.
Installation
Options
The
quality
of
installation
will
affect
the
performance
and
reliability
of
your
FUSION
amplifier.
For
maximum
performance
we
recommend
you
have
your
new
FUSION
amplifier
installed
by
an
authorised
FUSION
dealer.
Our
highly
skilled
dealers
have
vast
knowledge
of
our
products
and
their
installation
techniques
are
necessary
to
unleash
the
high
performance
capabilities
of
your
amplifier.
If
you
decide
to
connect
the
amplifier
yourself,
it
is
important
that
you
read
this
manual
carefully
and
throughout
before
starting.
Once
you
have
finished
reading
and
you
still
have
questions
regarding
installation,
we
recommend
your
FUSION
dealer.
Connection
FUSION
amplifiers
are
designed
to
work
within
a
10
to
16
volt
DC
range.
Before
any
wires
are
connected,
the
vessel's
electrical
system
should
be
checked
for
correct
voltage
supply
with
the
help
of
a
voltmeter.
First,
check
the
voltage
at
the
battery
with
the
ignition
in
the
OFF
position.
The
voltmeter
should
read
between
12
and
13.8
Volts.
If
your
vessel's
electrical
system
is
not
up
to
these
specification,
we
recommend
having
it
checked
by
an
auto
electrician
before
any
further
installation.
Once
the
vessel
is
checked,
make
certain
the
correct
cable
size
is
used.
We
recommend
using
the
following
cables
calculator
diagram
on
page
8
to
calculate
the
correct
power
cable
for
your
application.
Power
FUSION
amplifiers
should
be
wired
directly
to
the
battery
using
the
appropriate
sized
cable.
Start
at
the
vessel
battery
and
run
the
power
cable
through
to
the
amplifier.
FUSION
recommends
the
use
of
grommets
when
passing
the
power
cable
through
any
metal
wall
to
avoid
sharp
corners
or
panels
that
may
easily
cut
through
the
insulation
on
the
cable.
Avoid
running
the
power
cable
over
engine
components.
The
use
of
an
inline
fuse
or
circuit
breaker
is
a
must,
this
will
pre-
vent
the
risk
of
a
potential
fire
caused
be
a
short
in
your
power
cable.
Connect
the
fuse
holder
or
circuit
breaker
as
close
to
the
battery
positive
terminal
as
possible.
Use
a
fuse
or
circuit
breaker
of
equal
value
as
that
found
on
the
chassis
of
your
FUSION
amplifier.
You
may
now
connect
the
cable
to
the
battery,
but
remember
to
leave
the
fuse
out
or
circuit
breaker
off
until
all
other
cable
connections
are
made.
Ground
When
grounding
your
FUSION
amplifier,
locate
a
metal
area
close
to
the
amplifier
that
is
a
good
source
of
ground.
Once
again,
investigate
the
area
you
wish
to
use
for
electrical
wires,
vacuum
lines,
and
fuel
lines.
Use
either
a
wire
brush
or
sandpaper
to
eliminate
unwanted
paint.
This
will
supply
a
better
contact
for
your
ground.
Use
the
same
gauge
cable
for
