Protect Your Hearing, Serial Number | JL Audio A1400 specification

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.

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.

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.

Speaker Outputs

(pg. 8)

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

One of the standout features of the A1400 is its Class D amplifier technology. This design not only ensures high efficiency, allowing the amplifier to produce more power without generating excessive heat, but it also reduces the overall weight of the unit. The A1400 is capable of delivering 1400 watts of peak power, making it suitable for driving multiple speakers with ease, whether they are part of a full-range setup or a dedicated subwoofer stage.

The amplifier offers a fully flexible configuration, supporting 4-channel output, which enables users to run it in several different modes: 4-channel, 3-channel, or bridging it to a 2-channel operation for increased power to a pair of subwoofers. This versatility makes the A1400 adaptable for various audio setups, whether it's powering front and rear speakers or providing a rich low-frequency response.

In addition to its powerful output, the A1400 includes advanced technologies like differential balanced inputs, allowing for a clean signal transfer and reduced noise interference from external sources. This feature is particularly beneficial in automotive environments where electronic noise can impact sound quality.

The amplifier also comes equipped with a variable crossover network, enabling users to tailor the audio output to their specific needs. With this functionality, users can adjust the crossover frequency to ensure that each speaker is receiving the appropriate range of frequencies for optimal sound clarity and performance.
