Dear customer,

Congratulations on your purchase of a Bazooka BW high-performance
subwoofer. At Bazooka we are fanatics about accurate music reproduction.
Your selection of our products for your sound system indicates that quality
sound is also important to you too. At SAS, we take great pride in
manufacturing revolutionary audio products, and through the years of
engineering expertise, hand craftsmanship and critical testing procedures,
we have created the BW high-performance series of subwoofers. We hope
that you will take as much pride in owning and using one of these high-quality
audio products as we do designing and manufacturing them.

When properly installed and operated, your Bazooka BW subwoofer will give
you years of clean uninterrupted sound reproduction. Therefore, we urge you
to take a few minutes to carefully read through this manual. It will explain
how to properly build an enclosure to optimize performance and longevity of
the subwoofer.

Sound can be deceiving. Over time your hearing comfort level adapts to
higher volumes of sound. What may have sounded normal can actually be too
loud and harmful to your hearing. Guard against this by setting your
equipment at a safe level before your hearing adapts.

To establish a “safe level”,

Start with your volume control at a low setting.
Slowly increase the volume control until you can hear comfortably,

clearly and without distortion.
Once you have established a comfortable “sound level”, make a note

of this position and do not go above this setting

ENGLISH

Taking a minute to do this will help prevent your hearing from being damaged
and allow you to enjoy listening to music throughout your lifetime.

CALCULATING ENCLOSURE VOLUME

It is difficult to give exact box dimensions that are universal for all cars and
trucks. It is for this reason that you must be able to calculate the space in
which you have available in order to achieve the proper air volume required.
It is recommended to build your enclosure from 3/4” thick MDF (medium
density fiberboard). Make sure the enclosure is sealed air tight.

Calculating External Volume

ENGLISH

1.) To calculate box volume, measure the outside Width x Height x Depth of the
enclosure.

Example 12” x 14” x 9” = 1512”.

2.) Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inch total by 1728”.

Example 1512 1728 = .875 Cubic feet.

Calculating Internal Volume

1.) To calculate the internal (net) volume of the above box you must first
multiply the thickness of the wood you are using by Two (2).

Example 3/4” x 2 = 1.5”.

2.) Next subtract 1.5 from each of the outside measurements of the box.

Width Height Depth

12-1.5=10.5 14 -1.5 = 12.5 9 -1.5 = 7.5

3.) Multiply the new totals (H x W x D)

Example: 10.5 x 12.5 x 7.5 = 984.375

4.) Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inch total by 1728”

Example 984.375 1728 = .5696 Cubic feet.
