Cockpit Coaxial Speaker Systems
Thank you for purchasing a JL Audio Marine Coaxial Speaker System.
With proper installation, your new speakers will deliver
years of listening pleasure.
We strongly recommend that you have your new marine speakers
installed by your authorized JL Audio dealer.
The installation professionals employed by your dealer have
the necessary tools and experience to properly install your new speakers.
If you prefer to perform your own installation,
please read this instruction manual completely before
beginning the process.
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 a small enclosure.
TCX models are specifically engineered for
enclosed operation. This makes them ideal
for wakeboard tower systems or other small
enclosure applications.
Do not attempt to remove the tweeter from
the grille or the grille from the speaker!
The tweeter is permanently fixed to the grille
and its wiring is permanently attached to the
speaker frame. Attempting to remove the grille
or the tweeter will damage the speaker and this
damage will not be covered under warranty.

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 a few
seconds and the protection circuit will reset
itself automatically.

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.

It is absolutely vital that your coaxial speaker
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!
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 a collision. Please
review the mounting information carefully and
use the supplied marine-grade hardware to
mount this product.

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

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
