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.

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 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. 

ProteCt Your Hearing! 

We value you as a long-term customer. For 

that reason, we urge you to practice restraint in 
the operation of this product so as not to damage 
your hearing and that of others in your vehicle. 
Studies have shown that continuous exposure to 
high sound pressure levels can lead to permanent 
(irreparable) hearing loss. This and all other 
high-power amplifiers are capable of producing 
such high sound pressure levels when connected 
to a speaker system. Please limit your continuous 
exposure to high volume levels.

While driving, operate your audio system in 

a manner that still allows you to hear necessary 
noises to operate your vehicle safely (horns, 
sirens, etc.).

serial number  

In the event that your amplifier requires 

service or is ever stolen, you will need to have 
a record of the product’s serial number. Please 
take the time to enter that number in the space 
provided below. The serial number can be found 
on the bottom panel of the amplifier and on the 
amplifier packaging.

This amplifier is designed for operation in 

vehicles with 12 volt, negative-ground electrical 
systems. Use of this product in vehicles with 
positive ground and/or voltages other than 12V 
may result in damage to the product and will void 
the warranty.

This product is not certified or approved for 

use in aircraft.

Do not attempt to “bridge” the outputs of this 

amplifier with the outputs of a second amplifier, 
including an identical one.
