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.
