CCS AND TCS MODELS.•.
WHAT IS THE DIFFERENCE?
CCS 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 ifplaced in a
small enclosure.
TC5 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 offthe 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.
It
is absolutely vital that your component
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!
INTERCHANGEABLE LOGO BADGE
(Sport-Grille Models Only)
Interchangeable Logo Badges for Sport Grille
model component woofers are included to further
customize your installation. The design ofthe Sport
Grille allows for the JL Audio logo to be added in
your choice ofincluded colors and oriented in the
manner that best suits your installation.
NOTE: Aleft and aright badge of each
color is included. These two different
orientations
ensure the "JL Audio" Logo will
read correctly wherever positioned (most
commonly the 3:00 or 9:00 position).
Remove the adhesive backing from the badge
and affix the badge to the grille using the small
positioning hole as aguide. See diagram below.
TWEETER PROTECTION
The crossover networks are equipped with
an advanced electronic tweeter protection
circuit
designed to minimize the possibility
oftweeter
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 a few seconds and the
protection circuit will reset itself automatically.
SPEAKER PLACEMENT CONSIDERATIONS
Acomponent system gives you the ability to
place the woofer and tweeter separately in your
vessel. As a general rule, the tweeters should be
placed relatively close to the woofers for best tonal
balance and most coherent imaging (the closer, the
better). Any separation greater than 8 inches (20
cm) is likely to result in degraded sound quality.
Avoid placing tweeters where they will be
blocked by objects (including seated occupants).
When selecting amounting location, look at both
sides of the vessel to make sure that this location is
clear on both sides.

While these speakers are designed to be water and spray resistant, they are not designed to be submerged
or
to withstand high-pressure water spray. Please exercise care when washing your boat to avoid damaging
your speakers.
Do not install on submersibles, personal watercraft or any other vessel likely to be under
water at any time.
Prolonged exposure
to sound pressure levels in excess of 100dB can cause permanent hearing loss. This
high-performance speaker
can exceed this level. Please exercise restraint in its operation in order to preserve
your ability
to enjoy its fidelity.
When installing speakers in your
vessel, it is extremely important to secure them firmly. This applies not only
to the speakers themselves, but also any structure they are mounted to. If not firmly attached, the speakers
can become dangerous projectiles in acollision. Please review the mounting information carefully and use
the supplied marine-grade hardware to mount this product.

TWEETER INSTALLATION PROCEDURE
(SURFACE-MOUNT)
1) Choose a fiat mounting surface.
2) Drill al/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 ahand-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
#6 x 3/4-inch philips-head mounting screws and
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
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.
TWEETER INSTALLATION PROCEDURE
(FLUSH-MOU NT)
1) Choose a fiat mounting surface that has
sufficient depth to accept the mounting cup.
2) Cut a 1.87S-inch (48 mm) diameter hole.
3) Preassemble the spring clip and mounting cup
as shown in Diagram A, using the supplied
machine screw (Classic Grille Model shown.
Installation is the same for Sport Grille
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.
S) 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.

WOOFER INSTALLATION PROCEDURE
Diagram ( shows the typical installation
procedure into a
fiberglass panel, using the
supplied
hardware ((lassie Grille Model shown.
Installation
is the same for Sport Grille Models).
Always follow proper safety procedures Use eye-
protection at all times and adust mask and gloves
when cutting.
1) Choose a fiat mounting surface that has sufficient
depth
and air space behind it to accept the
component
woofer.
2) Cut a 6.25-inch (159 mm) diameter hole.
3) Run the speaker cable from the amplifier
output to the mounting location.
4) Place the woofer in the hole and mark the screw
hole locations using a sharp, pointed tool.
#8 SCREW: PILOT HOLE RECOMMENDATIONS
5) Remove the woofer and drill apilot hole (see
chart below) 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,
the output
wires to the tweeter and the jumper
wires to the woofer connections. See Wiring
Diagram on page 5.
7) Place the woofer, with its grille, into
the opening.
8) While holding the speaker firmly in its
mounting location, place the #8 x 13/8-inch
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.
