PLANNING YOUR INSTALLATION

It is important that you take the time to read  

this manual and that you plan out your 
installation carefully. The following are some 
considerations that you must take into account 
when planning your installation. 
 

Cooling Efficiency Considerations: 

The outer shell of your JL Audio amplifier is 

designed to remove heat from the amplifier 
circuitry. For optimum cooling performance, this 
outer shell should be exposed to as large a volume 
of air as possible. Enclosing the amplifier in a 
small, poorly ventilated chamber can lead to 
excessive heat build-up and degraded 
performance. If an installation calls for an 
enclosure around the amplifier, we recommend 
that this enclosure be ventilated with the aid  
of a fan. In normal applications, fan-cooling  
is not necessary. 

 

Mounting the amplifier upside down is  

strongly discouraged.

Safety Considerations: 

Your amplifier needs to be installed in a dry,  

well-ventilated environment and in a manner  
which does not interfere with your vessel’s factory 
installed electronic devices. You should also take 
the time to securely mount the amplifier using the 
supplied screws so that it does not come loose in 
the event of a collision or a sudden jolt to the vessel. 

 

Stupid Mistakes to Avoid:

•  Check before drilling any holes in your vessel to 

make sure that you will not be drilling through 
the hull, a fuel tank, fuel line, wiring harness or 
other vital vessel system.

•  Do not run system wiring outside or underneath 

the vessel. This is an extremely dangerous 
practice which can result in severe damage to 
your vessel and person.

•  Protect all system wires from sharp edges 

(metal, fiberglass, etc.) by carefully routing 
them, tying them down and using grommets 
and loom where appropriate.

•  Do not mount the amplifier in the engine 

compartment or in any other area that will 
expose the amplifier circuitry to the elements. 

While this amplifier is specially designed  

for marine applications, it is not waterproof 

and it should not be mounted where it is  

likely to get wet.
