PLANNING/MOUNTING YOUR SYSTEM

11

Planning Your System

Before beginning the installation, consider the following:

a.If you plan to expand your system by adding other components sometime in the future, ensure that adequate space is left, and cooling requirements are met.

If your radio/source is equipped with Pre-Amp outputs, it is possible to utilize them to drive an Amplifier and connecting (Amplifier) to the 2 rear speakers.

Then, use the built-in power of your radio to drive the 2 front speakers.

NOTE:

DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL) OUTPUTS, THAN SPEAKER (HIGH LEVEL) OUTPUTS.

b.Are your components matched? The RMS power rating of your speakers must be equal or greater than the Amplifier’s. They also must be 1-8 Ohms impedance (this information is normally printed on the speaker magnet).

c.Consider both the length of your leads, and routing when determining the mounting location. Pre-Amp input Jacks require a length of high quality shielded male to male RCA patch cord.

Mounting Your System

The mounting position of your Amplifier will have great effect on its ability to dissipate the heat generated during normal operation. It has an ample heat sink for heat dissipation, and also is designed with a thermal shut-down (for heat protection) circuit, having enough air directed over the cooling fins will improve heat dis- sipation dramatically. DO NOT enclose the amplifier in a small box or cover it so that air can not flow around the fins. Temperatures in car trunks have been measured as high as (155˚F) in the summer time. Since the thermal shut-down point for the Amplifier is (158˚F) it is easy to see that it must be mounted for maximum cooling capability. To achieve the maximum advantage of convection air flow in an enclosed trunk, mount the amplifier in a horizontal position. Cooling requirements are considerably relaxed when mounting inside the passenger compartment since the driver will not allow temperatures to reach a critical point. Floor mounting under the seat is usually satisfactory as long as there is at least 1 inch (2.54cm) above the Amplifier’s fins for ventilation.

a.Select a sutable location that is convenient for mounting, accessible for wiring and has ample room for air circulation and cooling.

b.Use the amplifier as a template to mark the mounting holes. Remove the amplifier and drill holes. Use extreme caution. Inspect underneath the surfaces before drilling!

c.Secure the Amplifier using the screws provided.

CAUTION:

Before connecting any wires to the amplifier, disconnect the ground lead from

 

the battery. Leave the ground lead disconnected until you are done wiring the

 

amplifier.

A12001DJ, A18001DJ specifications

AudioBahn is renowned in the world of car audio for producing powerful amplifiers that satisfy the needs of enthusiasts and audiophiles alike. Two notable models in their amplifier lineup are the A18001DJ and A12001DJ. These models showcase AudioBahn’s dedication to quality, performance, and innovative design.

The AudioBahn A18001DJ is a monoblock amplifier designed primarily to drive subwoofers. With an impressive output of 1800 watts RMS at 1 ohm, this amplifier can deliver deep and powerful bass, ensuring a dramatic listening experience. One of its standout features is the variable low-pass filter, which allows users to tailor the frequency response to their preferences, ensuring the subwoofer performs optimally. The A18001DJ also flaunts a sleek and robust design, making it not only a powerful performer but also a visually appealing component in any audio setup.

On the other hand, the A12001DJ is another monoblock amplifier that focuses on providing quality power but with a 1200 watts RMS output, ideal for those who want strong bass without needing to push their system to its limits. Similar to the A18001DJ, the A12001DJ features a variable low-pass filter, enabling customization of sound output. This is complemented by a built-in bass boost that can enhance low frequencies, allowing users to adjust the sound according to their taste.

Both amplifiers utilize advanced heat management technologies that incorporate a built-in fan. This ensures optimal performance without overheating, maintaining reliability even during extended use at high output levels. Additionally, the amplifiers come equipped with a remote bass level control, giving users the flexibility to adjust bass levels on-the-fly.

Another significant characteristic of both models is their durable construction. With a double-sided PCB design and high-grade electronic components, they are built to withstand the rigors of increased power demands while delivering consistent audio performance. The amplifiers also feature multiple protection circuits, such as short circuit and thermal protection, ensuring longevity and reliability in any audio setup.

In conclusion, the AudioBahn A18001DJ and A12001DJ amplifiers represent a blend of power, functionality, and design that is well-suited for car audio enthusiasts. Whether you’re after earth-shaking bass or simply looking to enhance your overall sound quality, these amplifiers provide the necessary features and reliability to elevate your listening experience.
