LED Equipped Models: 

Built-in, RGB LED lighting 

delivers beautiful accent illumination. LED functionality 
requires separate wiring at each speaker location. 
Adjustable control of RGB lighting requires the use of 
an RGB lighting controller (sold separately). For optimal 
performance, we recommend using the  
JL Audio marine lighting controller (MLC-RW).

 

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.

 

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.

 

Do not attempt to remove the tweeter or lighting 

LEDs from the grille. The tweeter and LEDs are 

permanently fixed to the grille and their wiring 

is permanently attached to the speaker frame. 

Attempting to remove the grille, tweeter or LEDs 

will damage the speaker and this damage will not 

be covered under warranty.

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.

 

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. Do not install on submersibles, personal 

watercraft or any other vessel likely to be under 

water at any time. Please exercise care when 

washing your boat to avoid damaging your 

speaker. Avoid contact with harsh chemicals 

or cleaning agents to prevent damage to the 

speaker’s finish that will not be covered under 

warranty. Wash with mild soap and rinse with 

freshwater only.
