INSTALLING
THE
SPEAKERS
Once
the mounting locations
have
been
established,
run
speaker
cables
from the amplifier
outputs to the mounting
locations.
If
you
are
running
cables
through
bulkheads,
drill
holes
for
the
cable
and
use
a urethane
or
plastic
grommet to
protect the
wire
from chafing
in
the
hole.
Make
sure
that the
cables
will
clear
any
mechanical
devices
in
the boat
and
secure
them with
wire
ties.
If
you
are
unsure
about
any
part of this
process,
please
contact your
JL
AUDIO
dealer
for
installation
help.
If
you
have
any
questions about
the
installation
or
setup
of
your
coaxial speaker system
not
covered
in
this manual, please contact
your
dealer
or
technical support.

COAXIAL INSTALLATION
PROCEDURE
Diagram
A
(page
7)
shows
the typical installation
procedure into a
fiberglass
panel,
using
the
supplied
hardware
(Classic
Grille
Model shown.
Installation
is
the
same
for Sport
Grille
Models).
Always
follow
proper
safety
procedures.
Use
eye-
protection
at
all
times
and
a dust
mask
and
gloves
when cutting.
1)
Choose
a flat mounting
surface
that
has
sufficient depth
and
air
space
behind it to
accept the
speaker.
2)
Using
a
hole
saw
or
jigsaw,
cut a mounting
hole
for
your
respective
speaker
model
(see
"Mounting
Hole
Diameter
(E)"
specifications,
page
2).
If
using
a
jigsaw,
tracing the
supplied
mounting
template
will
provide
you
with
an
accurate
line
on
which to
cut.
3)
Run
the
speaker
cable
from the amplifier
output to the mounting location.
4)
Place
the
speaker
in
the hole
(or
use
the
mounting template)
and
mark
the
screw
hole
locations
using
a
sharp,
pointed
tool.
5)
Remove
the
speaker
and
drill a pilot hole
(see
Pilot
Hole
Recommendation
chart,
page
7)
in
each
of
the
screw
locations.
It
is
also
advisable
to
use
a hand-driven
countersink tool
on
each
hole to further
inhibit gel-coat cracking
of
fiberglass
panels.
6)
Connect
the
speaker
wires
from
the
amplifier
and
the
jumper
wires
from
the
speaker's
attached
crossover
module
to
the
woofer
and
tweeter
connections.
See
Wiring
Diagram
on
page
5.
7)
Place
the
speaker
into the opening.
8)
While holding the
speaker
firmly
in
its
mounting location,
place
the
#8
x
1
3/8-inch
Phillips
pan-head mounting
screws
(with
washers)
and
snug
in
a
criss-cross
pattern,
then tighten with a
hand
screwdriver
in
a
criss-cross
pattern.
Non-standard
installations
may
require
different
hardware.
Always
use
marine-grade,
stainless-steel
fasteners
to
ensure
a
secure,
reliable
installation.
