Calculating Enclosures
It Is difficult
to
give exact box dimensions that are universal for ail 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 yow must convert cubic inches Into cubic feet. To do this, You must divide
the cubic inch total by
1728".
Example
1512 .;.1128= .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
12-1.5=10.5
Height
14-1.5=12.5
Depth
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 yow must convert cubic inches Into cubic feet.To do thls,you must divide
the cubic inch total by
1728"
Example
984.375.;.1728=. 5696
Cubic feet
