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 EL 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.
