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.

1.8 ohm 7.2 ohm

It is recommended to build your enclosure from ¾”
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

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: ¾” x2” = 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 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.
