OWNER’S MANUAL

300 W CLASS-A/B FOUR-CHANNEL FULL-RANGE AMPLIFIER

300/4v3

Thank you for purchasing a JLAudio amplifier

for your automotive sound system.

Your amplifier has been designed and manufactured to exacting

standards in order to ensure years of musical enjoyment in your

vehicle. For maximum performance and extended warranty

coverage, we highly recommend that you have your new amplifier

installed by an authorized JLAudio dealer. Your authorized

dealer has the training, expertise and installation equipment

to ensure optimum performance from this product. Should you

decide to install the amplifier yourself, please take the time

to read this manual thoroughly so as to familiarize yourself

with its installation requirements and setup procedures.

If you have any questions regarding the instructions in this

manual or any aspect of your amplifier’s operation, please

contact your authorized JLAudio dealer for assistance. If you

need further assistance, please call the JLAudio Technical

Support Department at (954) 443-1100 during business hours.

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 back 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, but

you still need to follow some basic guidelines:

• Amplifier mounted vertically with heat sink fins

pointing up: Optimum

• Amplifier mounted horizontally,

right side up: Good

• Amplifier mounted horizontally, but upside

down: Fair (not recommended if there is

less than 1 inch (2.5 cm) clearance above the

amplifier heat sinks)

• Amplifier mounted vertically with heat sink fins

pointing laterally: Fair

• Amplifier mounted vertically with heat sink fins

pointing down: Poor (not recommended)

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.

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 12V, 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.
