CALCULATING ENCLOSURES

It is difficult to give exact box dimensions that are universal for all vehicles. 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

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

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

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"

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

Width

12 - 1.5 = 10.5

14 - 1.5 = 12.5

Multiple the new totals (H x W x D) Example: 10.5 x 12.5 x 7.5 = 984.375

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.

Height

Depth

9 - 1.5 = 7.5
