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 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. 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.
