WARNING!
A speaker’s performance is only as good as it’s enclosure. Proper installation,
enclosure size and crossover frequency will maximize the overall performance of
the subwoofer. To properly design and build an enclosure, knowledge of wood-
working as well as the proper tools are required. We highly recommend that you
have your enclosure built by an authorized BASS INFERNO retailer. However, if
you decide to install it yourself, we have included the parameters of each driver and
recommended enclosure sizes. If after reviewing the enclosed information you have
any addition questions, please feel free to contact our technical dept.
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 airtight.
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 ÷ 1728” Cubic feet
2.) Next you must convert cubic inches into cubic feet. To do this, you must
divide the cubic inches 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.) Multiple the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = .5696
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.
Exposure to high pressure levels can cause hearing loss or
damage. Listening to your system at loud levels while driving, will
impair your ability to hear traffic sounds and emergency vehicles.
Use common sense when listening to your system.
While installing your subwoofer enclosure in the vehicle. Securely
fasten it to the frame or floorpan. If the enclosure is not secured
properly, there is danger of it becoming a projectile in a collision.
