Mounting
the
amplifier
1. Find a suitable location
in
the marine
vessel
in
which
to
mount
the amplifier.
2.
Make
sure there is sufficient air
circulation around
the
intended
mounting
location.
3.
Mark
the
location
for
the
mounting
hole screws by positioning the amplifier
where
you wish
to
install it. Use a
scribe
or
mounting
screw, inserted
through
each
of
the
amp's
mounting
holes,
to
mark
the
mounting
surlace.
If
the
mounting
surlace
is
carpeted,
measure
the hole
centers
and
mark
with
a felt
tip
pen.
4. Drill
pilot
holes
in
the
mounting
surface for the mounting screws. Place
the
amplifier
in
position,
and
attach
the
amplifier
to
the
mounting
surlace
securely uSing screws.

Be
sure you
understand
all
the connections before you proceed.
1. Connect the
power
ground
terminal
to
tr.e
closest
point
on
the
chassis
of
the
marine
vessel. Keep
tris
ground
wire
to
less than 39" (100 em) h length.
Use
8
gauge
(or heavier) wire.
2.

fJse holder within
18" (45 em)
of
the car battery. and run
8 gauge (or heavier)
cable
from
this
fuse
to
the
amplifier
location.
4. Check that trfJ fuse holder is empty.
Then COllnect the fuse

connection
on
the amplifier.
5.
If multip:e amplifiers are being used
in
your
system, either:
• Run a separate
pair
of
cables
from
the battery
and
a chassis
ground
pOint
to
each amplifier. Each
(+)
cable
must
have its
own
inline fuse.
-or-
• Run a #0
or
#2
cable
from the fuse
holder at the
battery
to
a
distribution
block
at
or
near the amplifier's location,
Then run separate
cables
from
the
amplifier
to
this distribution
block
and
to
independent chassis ground points.
6,
Connect
all line
inputs
and
outputs
(if
used) using high-quality cables. Connect
all speakers,
following
the
diagrams
in
this manual.
Be
sure
to
observe
proper
polarity
to
avoid
audio
phase
problems.
7. Insert tuse(s)
into
the
battery
fuse
holder(s).
8.
Recheck
all
connections
before
powering
up
the
amplifier.
9.
Sel
all level
controls
to
min,imum
position,
and
set all
crossover
controls/switches
to
the desired
frequency
poillts.
10.
Power
up the
head
unit
and
the
amplifier. Then
s~t
the
volume
control
on
the
nead unit
to
about
3/4 volume,
and
adjust the amplifier's
input

control(s)
to
just
below
the 'level
of

11. Further fine tuning
of
the
various
controls may be necessary
to
obtain best
results.
Don't

ONLY
to
