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 using the supplied

screws 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.

Serial Number:

INSTALLATION APPLICATIONS

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.
