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 basedR&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.

WARNING
Continuous exposure to sound pressure levels over 100 dB may cause
permanent hearing loss. High powered autosound systems may produce sound
pressure levels well over 135dB. Need we say more! Use common sense.
If after reading this manual, you still have questions regarding your product, we
recommend that you see your nearest Audiobahn Dealer. A list of Authorized
Audiobahn Dealers can be found on our web page. If you need further assistance, feel
free to call us at [phone] and ask for the Technical Department. Be sure to have
the model number, date of purchase, and invoice number available when you call.
The model number can be located on the outside of the carton. Record this in the space
provided below along with the date of purchase. It is a good idea to keep your receipt
with this, as you will need it in the case of a warranty repair or exchange.

Capacitor Introduction
5
When installed properly, your new stiffening capacitor will provide years of dependable
service. There are many benefits of adding a stiffening capacitor. The most significant benefit is the
capacitors ability to improve bass performance in your sound system. This is possible due to the
voltage stabilizing effects of the capacitor.
When an audio system needs to deliver an instantaneous bass peak, the vehicle's
electrical system often cannot provide enough power. This means that the system voltage drops
substantially to a point that the amplifiers are unable to produce their rated power. This is referred to
as clipping. When an amplifier clips, it will cause distortion and can cause amplifier and / or speaker
damage.
Stiffening capacitors are able to store large amounts of energy in preparation of these
bass peaks. When a bass peak occurs, the stiffening capacitor delivers power to supplement the
system voltage and prevent amplifier clipping. This retains amplifier output power, thus improving
bass response and increases amplifier and speaker life span.
Another beneficial effect of capacitors is their ability to filter the current produced by the
vehicle's alternator. This alternator current, can cause noise (alternator whine) in the audio system.
A capacitor will help reduce or eliminate this "alternator whine" and popping.
We recommend using 1 farad of capacitance for every 1000 watts of amplifier output. This
is a general rule of thumb and may be adjusted up or down depending on the efficiency, current
draw, and design of the amplifiers being used.

Installation and Mounting

Please refer to the following drawing to install screws into the mounting tabs of the capacitor's side rails.
Use the lock screws to mount the capacitor brackets to the vehicle. Make sure the capacitor is securely
mounted using all four brackets. Brackets are supplied with all rack mount amplifiers.
