CCX AND TCX MODELS •••
WHAT IS THE DIFFERENCE?
CCX models have woofers specifically designed
for infinite-baffle applications. In plain english,
this means that they are designed to operate
without an enclosure behind them. The bass
response of the speaker will suffer significantly if
placed in asmall enclosure.

TCX models are specifically engineered for
enclosed operation. This makes them ideal
for wakeboard tower systems or other small
enclosure applications.

BEFORE YOU BEGIN INSTALLING
•Turn off the audio system. It is also advisable
to disconnect your battery system whenever
performing installation work.
•Before cutting, drilling
or inserting any screw,
check clearances on both sides
of the planned
mounting surface. Also check for any potential
obstacles, such as wiring harnesses, fuel lines,
hydraulic lines, etc. Check both sides
of the
vessel before cutting any holes.
•Wear protective eyewear at all times
and adust
mask and gloves when drilling or cutting.

system is connected as shown in
this manual.
Failure
to connect the system as shown will
result
in damage to your speakers which
is
NOT covered under warranty. Do not
substitute different crossover networks!
mCAUTIONI
While these speakers aredesigned to bewater
and sprayresistant, theyare not designed to
be
submerged or to withstand high-pressure water
spray. Please exercise care when washingyour
boat
to avoid damaging your speakers. Donot
install
on submersibles, personalwatercraft or any
othervessel likely

of lOOdB can cause permanent hearing
loss. This high-performance speaker can
exceed this level. Please exercise restraint in its
operation
in order to preserve yourability to

When installing speakers in your vessel, it is
extremely important to secure them firmly. This

dangerous projectiles in acollision. Please
review the
mounting information carefully and
use the supplied marine-grade hardware to
mount this product.
TWEETER PROTECTION
The crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility
of tweeter
failure. This electronic device monitors current
going to the tweeter and will disconnect the
tweeter from the signal when it senses overload.
Should this occur while listening to the audio
system, simply reduce the volume for afew
seconds and the protection circuit will reset
itselfautomatically.

INSTALLING THE SPEAKERS
Once the mountinglocations 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 aurethane
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.

using the supplied hardware. Always follow proper
safety procedures. Use eye-protection at all times
and adust mask and gloves when cutting.
1) Choose aflat mounting surface that has
sufficient depth and air space behind it to
accept the speaker.
2) Using ahole saw orjigsaw, cut amounting
hole for your respective speaker model
(see
"Mounting Hole Diameter (E)" specifications,
page
2). If using ajigsaw, 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 asharp, pointed tool.
5} Remove the speaker and drill apilot hole (see
Pilot Hole Recommendation chart,
page
7) in each of the screw locations.
It is also advisable to use ahand-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 acriss-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 asecure, reliable installation.
