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.

Capacitor Introduction

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.

Troubleshooting

Should you encounter a problem with your capacitor, you can follow the steps below to

make sure that it is working properly.

1. Follow all power (+) and ground (-) connections to and from the capacitor. Make sure

there are no kinks in the wire and no cuts either. If there is a problem in the wiring, make sure to use

new wire and place the wire in a good location where it will not be roughed up and abused.

2. If using a capacitor with a digital display, you can visually check the capacitor to see if it

is functioning correctly. After charging the capacitor with the provided bulb, remove the bulb and

attach the power wire. If the volt-meter changes slowly, then the capacitor is properly holding the

charge. If the display rapidly decreases and shuts off, then the cap is not properly holding a charge.

3. In the case that you find that step 2 shows your capacitor is not holding a charge, you

may want to take the capacitor to an authorized dealer to have them run a capacitance test on the

capacitor.

Warning / Disclaimer

WARNING

Investigate the layout of your automobile thoroughly before drilling or cutting any holes.
Take care when you work near the gas tanks, gas lines, hydraulic lines, and electrical
wiring. Attach the system securely 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 pinching or damage from nearby objects.

The +12V DC power wire must be fused at the battery positive terminal connection.
Before making or breaking power connections at the system power terminals,
disconnect the +12V wire at the battery end. Confirm your radio/head unit and/or other
equiptment is turned off while connecting the input jacks and speaker terminals.
If you need to replace the power fuse, replace it only with a fuse identical to that
supplied with the system. Using a fuse of different type or rating may result in damage to

this system which is not covered by the warranty.
