Calculating Enclosures
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" x9" = 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 h - 1728 = .875 Cubic feet
Calculating Internal Volume
1) To calculate the internal (net) volumn 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 12*1.5=10.5 Height 14-1.5=12,5 Depth 9-1.5 =7.5
3) Muitipfy 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-r1728 =. 5696 Cubic feet
