he 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 that does not know a voice coil from a
spider. We are all here 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.
*To learn more about "TEAM AUDIOBAHN" please give us a call, see our
website at www.audiobahninc.com, or email us at team@audiobahninc.com to learn

1. LOW LEVEL INPUT RCA JACKS
These Inputs are for signal cables from the source unit. Always use high quality shielded
RCA cables.
2. SELECT
3. INPUT BALANCED
BAL(Balance): Min Din Jack, NOR(Normal): RCA Phone Jack.
4. BRIDGED MODE
Note that on amp must be set to "Master" position while the other is set to "Slave".
5. BASS REMOTE
This is the connection for the bass control knob which, cotrols the bass boost signal level.
6. SPEAKER TERMINALS
These nickel plated connectors can accept from 16 to 8 gage wire.
Be careful to observe proper polarity when connecting the cables.
7. BATTERY POSITIVE TERMINAL
Due to power requirements of the Amplifier, this connection should be made directly to the
positive (+) terminal of battery for a safety measure, install an in-line fuse Holder (not included)
as close to the battery positive (+) terminal as possible with an ampere rating;
not to exceed the total value of fuses in Amp.
8. REMOTE TURN-ON INPUT
T o remote or power antenna output of car stereo. This amplifier is turned "ON" remotely
when the vehicle's stereo is turned "ON"
NOTE: IF YOUR RADIO DOES NOT HAVE +12VOL T OUTPUT LEAD WHEN THE RADIO
IS TURNED ON, THE "REMOTE" TERMINAL ON THE AMPLIFIER CAN BE
CONNECTED TO VEHICLES ACCESSORY CIRCUIT THAT IS LIVE WHEN THE
KEY IS "ON".
9. CHASSIS GROUND
To avoid unwanted ignition noise caused by ground loops, it is essential that the Amplifier be
grounded to a clean, bare, metal surface of the vehicle's chassis.
NOTE: GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT(1 METER.)

10. LED INDICATOR
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 RED LED indicator on the side panel will be illuminated, indicating the
amplifier has gone into a self-preservation mode.
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.
If you observe that th Protection LED is lit, please check the system carefully to determine
what has caused the protection circuit to engage. The amplifier can be reset by turning the
remote 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
up the amplifier again.
11. BASS BOOST GAIN ADJUSTMENT
This control adjusts bass boost gain for the amplifier's speaker output(0 to 18dB).
It will only work in LPF mode.
12. VARIABLE LOW PASS FILTER (50Hz to 150Hz)
For use as a dedicated subwoofer channel, set filter switch to "LPF". Adjust variable crossover
frequency with control as desired. The amplifier input circuit filters out everything about 50Hz ...
150Hz(dependent on the adjustment of the frequency control).
13. VARIABLE SUBSONIC FILTER
This control adjusts the frequency(15Hz to 40Hz)
14. PHASE SHIFT SWITCH(0 to 180 degrees)
Allows you to change the phase of your subwoofer from 0 to 180 degrees to help compensate
for timing differences between mid and sub drivers.
15. INPUT SENSITIVITY ADJUSTMENT
This control adjusts the amplifier's input sensitivity. Input sensitivity is variable from 200 millivolts
to 8 volts. Clockwise increases sensitivity and counterclockwise decrease sensitivity.
This knob is not a volume control for the amplifier. The amplifier can be driven to full power with
a wide range of signal levels. A lower signal level will require increased sensitivity for full power
while a higher signal level will require decreased sensitivity.

The amplifier automatically turns on a few seconds after you turn your vehicle's ignition
switch to ACC or ON or turn on your auto sound system, depending on how you wired
the system. The POWER indicator on the top of the amplifier lights when the amplifier is on.
Important : Your amplifier requires 30 amps or more of power from your vehicle's battery
during operation. To protect your battery from discharging, do not operate
the amplifier unless your vehicle is running.
NOTE : Raising the Bass frequency allows higher frequencies to reach the bass
speakers while blocking lower frequencies from midrange speakers.
Lowering the Bass frequency allows lower frequencies to reach the
midrange speakers while blocking higher frequencies from bass speakers.

For the best performance, you must set LEVEL (MIN/MAX) on the side of the amplifier to
adjust the level of the audio signals that enter the amplifier.
1. Use a screwdriver to turn LEVEL (MIN/MAX) fully counterclockwise to MIN>
2. Turn the auto sound system's volume control to about one-third of its full range.
3. Adjust LEVEL (MIN/MAX) to a comfortable listening level.
4. Turn up the auto sound system's volume control until the sound begins to distort. Then
immediately turn the volume down to a point just before where the distortion began.
Caution : Never turn up the auto sound system's volume control more than needed to
adjust the audio level, more than two thirds of its maximum volume.
5. Adjust LEVEL (MIN/MAX) until the sound is at the maximum level you want the amplifier
to produce.
6. Adjust the auto sound system's volume control to a comfortable listening level.

Investigate the layout of your automobile thoroughly before
drilling or cutting any holes to the automobile. Take much care
when you work near or around the gas lines, hydraulic lines, and
electrical wiring. Do not use a power amplifier unmounted and
make sure to secure the entire system to the automobile to
prevent damage, particularly in the event of an accident. Do not
mount the system so that the wire connections are unprotected
or are subject to pincing or damage from nearby objects.
The +12V DC power wire must be fused at the battery positive
terminal connection.(16" max. distance is recommended) Before
making or breaking power connections at the system power
terminals, disconnect the +12V wire at the battery end. If you need
to replace any power fuses, make sure to replace the fuse with the
exact same size rating. Using a different type or rating may result
in damage to this system which is not covered by the warranty.
