The Audiobahn Way
To bring the product to market that excites the consumer through
sound and vision from an orientation of integrity and customer service. We
make you look as good as you sound. We strive to take car audio to an
extreme the world has never seen, and a world that never stops evolving.
Audiobahn was established in 1997 with one long-term goal in mind,
"Build it Bigger, Badder, & Better, and the people will take notice!" We
back this statement with an engineering team that has brought home several
Innovations, Design & Engineering Showcase Awards, and a marketing team
from around the world that spends countless hours developing our no
compromise products to satisfy the most discriminating enthusiasts.
Our global manufacturing facilities feature ISO9002 ratings (the highest
level of quality control awarded in the electronics manufacturing industry), fully
robotic assembly lines and a state of the art, California based R & D
laboratory.
Due to overwhelming response from our competitors, and our goal to
participate in even more events this year, we created *"TEAM AUDIOBAHN."
This organization is designed to create a support network along with shirts and
perks for team members. "TEAM AUDIOBAHN" is not only for the diehard
competitor, but also for anyone that loves car audio as much as we do. With
four levels of play, one is right for you to get started in the Audiobahn family.
Our Technical Department and entire staff look to strive above and
beyond the rest of the pack by going that extra mile to help you out. Whether
you happen to be a veteran competitor, or a beginner car audio enthusiast
who does not know a voice coil from a spider. We are all her to help you get
the best system you can with what you have.
Judge for yourself, and remember what it's all about, "If it's not
Bigger, Badder & Better, it's not Audiobahn." If audio is your life,
Audiobahn is the brand for you! We make you look as good as you sound.
People never stop trying to get the best product, so we will never stop making
it.

Due to the power requirements of the amplifier, this connection should be made directly to the positive (+)
terminal of the battery. For a safety measure, install an in-line fuse holder (not included) as close to the battery
positive (+) as possible with an apmere rating not to exceed the total value of fuses in the amp.

This control adjusts the amplifier's sensitivity to match the signal strength coming from the source unit. Input
sensitivity is variable from 200 Millivolts to 8 volts. Clockwise increases sensitivity. Counterclockwise decreases
sensitivity. THE KNOB IS NOT A VOLUME CONTROL. A lower signal level will require increased sensitivity for
full power. A higher signal will require decreased sensitivity.

-PWR (Power) : This BLUE LED will illuminate when the amplifier is turned "ON". If it fails to illuminate, check the power
connections to the amplifier and fuses.
- PROT (Protection) : The amplifier protection circuitry will disable the amplifier if input overload, short circuit, or extremely
high temperature conditions are detected. When the protection mode is in operation, the LED indicator on the side
panel will be illuminated, indicating the amplifier has gone into a self-preservation mode.
If you observe that the protection LED is lit, please check the system carefully to determine what has caused the
protection circuit to engage. The amplifier shut down due to a thermal overload condition, please allow it to cool
down before restarting. If the amplifier shut down because of an input overload or short circuit, be sure to repair these
conditions before attempting to power up the amplifier again.

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.
NOTE:
DISTORTION LEVEL IS CONSIDERABLY LOWER FROM PRE-AMP (LOW LEVEL)
OUTPUTS, THAN SPEAKER (HIGH LEVEL) OUTPUTS.
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.
a. Select a suitable 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.
The mounting position of your Amplifier will have a 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 dissipation 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 (2.54 cm) above the Amplifier's fins for ventilation.
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.
