years of listening pleasure.  
We strongly recommend that you have your new marine speakers  
installed by your authorized JL Audio dealer.

the necessary tools and experience to properly install your new speakers.

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.  
•ꢀBeforeꢀcutting,ꢀdrillingꢀorꢀinsertingꢀanyꢀscrew,ꢀ  
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
