cooling efficiency considerations: 

Your JL Audio amplifier employs an 

advanced type of heat management, called 
RealSink™. This feature takes advantage of 
convection and radiation effects to remove 
heat from the amplifier circuitry. For optimum 
cooling performance, the vertical heat sinks 
located at the sides of the amplifier 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.

If mounting the amplifier under a seat,  

make sure there is at least 1 inch (2.5 cm) of  
space above the amplifier’s outer shell to permit  
proper cooling.

safety considerations: 

Your amplifier needs to be installed in a dry,  

well-ventilated environment and in a manner  
which does not interfere with your vehicle’s safety 
equipment (air bags, seat belt systems, ABS brake 
systems, etc.). You should also take the time to 
securely mount the amplifier using appropriate 
hardware so that it does not come loose in the 
event of a collision or a sudden jolt to the vehicle.

 

stupid mistakes to avoid: 
•  

Check before drilling any holes in your vehicle 
to make sure that you will not be drilling 
through a gas tank, brake line, wiring harness or 
other vital vehicle system.

•  Do not run system wiring outside or underneath 

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

•  Protect all system wires from sharp metal  

edges and wear by carefully routing them,  
tying them down and using grommets and  
loom where appropriate.

•  Do not mount the amplifier in the engine 

compartment, under the vehicle, on the roof  
or in any other area that will expose the 
amplifier circuitry to the elements.
