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 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 vessel. 

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. 

stupid mistakes to avoid 
•  

Check before drilling any holes in your vessel to 

make sure that you will not be drilling through 

a gas tank, brake 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 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 vessel, 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 vessel. 

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 vessel 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. 

 

Serial Number:  

 

installation aPPliCations

This amplifier is designed for operation in 

vessels with 12 volt, negative-ground electrical 

systems. Use of this product in vessels 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.

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.
