Dear customer,
Congratulations on your purchase of a Bazooka PMW highperformance 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 RSW highperformance 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 PMW 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
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
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.
