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 as-
sembly lines and a state of the art, California based R & D laboratory.
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, Bad-
der & 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

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.

PROTECT
-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.

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 Amplier and connecting (Amplier) 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 Amplier’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 Amplier 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 ns will improve heat dis-
sipation dramatically. DO NOT enclose the amplier in a small box or cover it so that air can not ow around
the ns. Temperatures in car trunks have been measured as high as (155˚F) in the summer time. Since the
thermal shut-down point for the Amplier 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 ow in an enclosed trunk, mount the
amplier 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 Amplier’s ns 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 amplier as a template to mark the mounting holes. Remove the amplier and
drill holes. Use extreme caution. Inspect underneath the surfaces before drilling!
c. Secure the Amplier using the screws provided.
CAUTION: Before connecting any wires to the amplier, disconnect the ground lead from
the battery. Leave the ground lead disconnected until you are done wiring the
amplier.
