TWEETER INSTALLATION PROCEDURE
(SURFACE-MOUNT)
1) Choose a flat mounting surface.
2) Drill a 1/4-inch (6 mm) diameter hole at the
center of your desired mounting location (to
pass the tweeter wires). To prevent cracking,
start with a smaller drill bit and gradually work
up the target diameter.
3) Place the surface mount cup at the desired
location and orientation. Then mark the
three mounting screw locations with a sharp,
pointed tool.
4) Remove the mounting cup and drill three
3/32-inch (2.38 mm) diameter pilot holes at the
locations you just marked. It is also advisable
to use a hand-driven countersink tool on each
hole to further inhibit gel-coat cracking of
fiberglass panels. Depending on the thickness
of the mounting surface, it may be necessary to
enlarge the screw holes slightly.
5) Place the mounting cup and align it over the holes
you just drilled. Then insert three of the supplied

tighten gradually with a hand screwdriver until the

tighten gradually with a hand screwdriver until the
cup is tight against the surface.
6) Insert the tweeter wires through the center
hole and then snap the tweeter into place by
pushing in firmly.
7) Connect the tweeter wires to the tweeter
output terminals on the crossover. See Wiring
Diagram on page 4.
INSTALLING THE SPEAKERS

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

TWEETER INSTALLATION PROCEDURE
(FLUSH-MOUNT)
1) Choose a flat mounting surface that has
sufficient depth to accept the mounting cup.
2) Cut a 1.875-inch (48 mm) diameter hole.
3) Preassemble the spring clip and mounting cup
as shown in Diagram A, using the supplied
machine screw

Models). Do not tighten fully.
4) Insert the cup into the mounting hole so that
the spring clip expands on the inside of the
mounting surface.
5) While holding the tweeter cup in the desired
orientation, tighten the machine screw (with a
hand screwdriver) until the cup is tight in the hole.
6) Insert the tweeter wires through one of the
slots in the cup and then snap the tweeter into
place by pushing in firmly.
7) Connect the tweeter wires to the tweeter
output terminals on the crossover. See Wiring
Diagram on page 5.
