how to design box

[budahbuddy803 10+ year member]

Are there any websites or formula's to get box plans? I would like it to be 3/4"s MDF and a box to fit into a 29"deep x 21"wide x 20"tall area. That is the size of the smaller seat in the back of my 4 dr. dodge dakota and i would like to put it in a 2.75ft^3 box tuned to 30hz. Is this possible, if not what should the demensions of the box be to be 1.55ft^3 sealed? Needing to build box soon. Other space can be used, but that is what i really want.

there are people here that will design one for you... but for a box... length x height x width divided by 1728 will give u the volume of your box. and those measuerments should be internal

so a box that was 29"x21"x20" would be 7.164352 ft^3?
