Woofer Introduction
4
Audiobahn woofers are a low frequency driver designed primarily for use in small sealed or
vented enclosures depending on the model of sub. Please check the specifications in this
manual, our website at www.audiobahn.com. As specifications and parameters are subject
to change, we highly advise always checking our website or calling us for the most current
information. By utilizing the latest materials and construction design and techniques, we
are able to offer a sub woofer with optimized low frequency response..

WIRING
Audiobahn recommends using at least 16-gauge wire with your new speaker system. Thinner gauge wire may easily be severed and can cause damage to your system should any
bare wires come in contact with the vehicles chassis.
Makes sure that your audio system is off while installing and connecting your new Audiobahn Speakers. Failure to do so could result in damaging the speaker beyond repair. This
is not something that would be covered under the manufacturer warranty.
Be sure to route the wires to the speakers with the insulated terminal ending at the speaker. This will insure a good contact with the speaker. If you need to shorten the speaker
lead, do so on the opposite end of the insulated terminals or the bare end.
Be sure the polarity is correct at all times. The speaker leads are color coded for negative
and positive. Make sure that the leads connected to the positive terminal of your amplifier
or source unit is correctly connected to the positive terminal of the speaker.
To insure long-term reliability all bare wires and wire-to-wire connections should be soldered and insulated with heat shrink or electricians tape. Under no circumstances should
you leave any bare wires uncovered, as this can and will lead to the failure of your speakers and possibly other components.
When mounting in a door it is imperative to have the right amount of slack in the connecting wire as to not get crimped or torn when the door is opened or closed. Avoid areas of
the door jam that pinch. This will cause damage to the speaker and other components over
long-term use.
Once the speaker wiring is complete, you can connect the opposite end to the amplifier or
source unit. Again, be sure to observe correct polarity. Solder and wrap all stripped connections.
ENCLOSURE AND SETUP
6
Building an Enclosure
To work properly, the walls of the enclosure must be rigid and not flex when subjected to
high pressure generated by the speaker’s operation. For optimum performance, we recommend using 3/4” MDF (Medium Density Fiberboard) and internal bracing. The enclosure
should be glued together along with support of screws or nails. Because MDF is porous, it
is suggested that you seal the outside with polyurethane prior to painting or carpeting.
Calculating Volume
Calculating is merely a matter of measuring the dimensions in inches, and using the following formula:
Box Volume = (Height) x (Width) x(Depth) divided by 1728. This will give you the volume of
the box in cubic feet.
If two facing sides are uneven length, add them together, and divide by 2 to take the average. Using this number will give you the volume without the necessity of calculating the box
in sections, and adding the sections together. The thickness of the baffle material reduces
the internal volume so this must be subtracted from the outside dimensions to determine
the internal volume. The amount of air displaced by each model is listed on the specifications sheet in this manual and should also be subtracted from the gross volume calculation.
All box parameters include displacement for ports and subs. These specs do not include
the volume of the material used to build the box, so this must still be factored into the calculation.
Subwoofer Crossover
There are two operational types of crossovers, passive and active. Passive crossovers
(coils and conductors) are placed on the speaker leads between the amplifier and the
speaker. An active crossover is an electronic filter which separates the audio signal fed to
different amplifiers. For optimum subwoofer performance, we recommend using an active
80-100Hz low pass crossover at 12/dB/octive.
Parameters

AMD Midbass and Box Parameters
All ports listed are circle ports unless otherwise stated. Surface area of a circle port = (3.14) X (radius) (squared)
Remember to build your box to the total volume, not just air space, as total volume includes all displacement.

All sealed boxes already include the displacement for the subwoofer. NR = (Not Recommended)
The larger a sealed box is, the lower the sub will play, but the less power it will handle. The smaller a sealed box is, the
higher the frequency the sub will play, and the more power it will handle.
Troubleshooting
8
If you start having problems with distorted sound or loss performance after installing
your subs, you can follow the instructions below to try and locate what is causing the
problem.
1. If you have any distorted sound, loss of performance, or rattling from your subs,
check the connections running from your amplifier or other processor to the box. You
will also want to check the connections inside the box to make sure no wires have
become unhooked or are loose.
2. If the above does not solve the problem, check your enclosure thoroughly to see if
there are any leaks, cracks, or broken pieces. Any loss of structural integrity of your
enclosure can cause significant performance loss and distortion.
3. The next step you can take is to remove the subs and look for any burned wire leads
or separated components. You can normally smell something burning when a sub
blows or is going bad. Sometimes when you play subs to hard for too long, they will
start to heat up.
4. If none of the above steps solve the problem, you will want to start looking at the
other components in the vehicle. Start by checking all connections to and from the
box, amplifier, source unit, or any other processors you may be using. You will need
to reference to that particular manufacturer for any setting configurations or troubleshooting.
Warning And Disclaimer
9
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.
