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.
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!

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
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. Capacitance

Before making or breaking any electrical connections, please make sure to
read the following instructions on how to properly charge and discharge the capacitor.
Not following the charge / discharge instructions can lead to permanent damage to the
capacitor, which is not covered under the manufacturer warranty.
After mounting the capacitor in its final position, attach the ground to the capacitor and the chassis grounding location. Next hold the supplied bulb between the
(+) positive battery lead and the (+) positive terminal of the capacitor. If using a bulb, it
should light up for a short time (normally 15-30 seconds or so) and then go out. After
waiting for the capacitor to charge, remove the bulb or resistor and immediately attach
the power (+) cable to the capacitor. The best way to ensure the cap is charged best is
to keep the bulb attached until you touch the main power (+) wire to the capacitor, then
remove it.
If you plan to store your vehicle or plan on not using the system for a long
period of time, we suggest to remove the capacitor. Anytime you disconnect the capacitor’s power wire from the battery, you need to properly discharge the capacitor. This is
done by using the same supplied bulb as you used for charging the capacitor. Take the
bulb and place the ends across the negative (-) and positive (+) terminals of the capacitor. This will cause the capacitor to safely discharge so it can be stored away.
Installing And Mounting
For maximum performance, the capacitor should be installed as close to your
amplifier(s) as possible. The ideal location is one which allows for short wiring runs
while keeping the capacitors somewhat isolated from the heat created by the amplifier
system. The positive (+) power wire should be kept as short as possible and be connected to the amplifier’s battery supply input. We recommend that a high performance
distribution block be used to create a splice into this cable (see Fig. 1). You may also
use the capacitor itself as a distribution block by adding multiple power wires to the
terminals located on the top of the capacitor.
No fuses should be installed in the wire between the capacitor and the amplifier
system (make sure there is an appropriate fuse at the battery in the main power supply
cable). The ground cable for the capacitor should also be made as short as possible
and be connected directly to the vehicle chassis at a bare metal location. Do not ground
the capacitor directly to the amplifier ground terminal or ground cable. The capacitor
and all other components in the system should be grounded using separate ground
cables. It is ok to ground them to the same point on the chassis or frame, just not connected directly to eachother. (see Fig. 1) The positive (+) and negative (-) wires for the
capacitor should be the same gauge as the amplifier’s power and ground cables.

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 And Disclaimer
Investigate the layout of your automobile thoroughly before drilling or cutting any holes. Take care
when you work near gas tanks, gas lines, hydraulic lines, and electrical wiring. Do not use the power amplifier unmounted. 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 equipment 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 a different type or rating may result in damage to this system which is not covered by
the warranty.
