what size box for 3.5" speakers

[budahbuddy803 10+ year member]

i have two pioneer 3.5" coaxils i bought from walmart to replace stock in my old car but now that i dont have a real use for them in my car i want to build a box for them and hook them up to my home theater or computer setup.

The thing is how big of a box would i need or where could i find info like that? I figure that would be a simple first box. I would do a sealed box with two different chambers. Does anyone have any guesses on what size box i should make? and they are 20rms@ 4ohm i could go down to like 1/2" or maybe 1/4" mdf dont you think. I dont think these guys will be doing much flexing.

Just do like a .3 sealed box, or a ported box tuned to like 45 or something. Wall socket maybe?
