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 (800)488-8595 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
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
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
You can find the mounting screw sin the attached hardware bag.. Then use the lock screws to hold
the tab in the car's wall. Make sure the whole unit does not move after you install all four tabs.
A) Blue lite digital voltage meter with 4 digit readout that can measure 0.01 DCV.
B) Positive pole distribution block with 4 maxi fuses. Negative pole distribution block. These �
connections can offer a simple alternative to using various power and ground distribution blocks �
when connecting multiple amplifiers and accessories.
C) Reverse pole connecting PCB buzz warning function. If the capacitor is connected incorrectly by �
reversing the positive and negative wires during the installation process, the PCB will issue a 45
second noise to warn you.
D) High-end platinum plated 100% solid brass parts and chrome plated metal cover.
E) Over voltage limit and low battery voltage limit warning. When the system voltage peeks over �
16V (DC) or LESS than 10V (DC), the buzzer on the PCB will issue an audible noise warning.
F) Multiple small capacitance capacitors linked together to provide the lowest inner E.S.R. and the �
largest momentary discharge.
Charging / Discharging
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 or
resistor 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. If using a resistor, just wait the appropriate time of
15-30 seconds. 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 or resistor attached until you
touch the main power (+) wire to the capacitor, then remove it.
Follow the attached wiring diagram to connect all wiring and parts. Below is an illustration showing
correct wiring for the capacitor.
Dicharging the Capacitor
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
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

Warning / Disclaimer
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.
Specifications are subject to change with out notice.
