determining "volume" measurement of enclosure on sight?

[kingsxman 10+ year member]

It seems that most sealed enclosures are all made about the same: 3/4 in mdf with some sort of terminal(s) connections on the box. Glue around the inside and gray/black carpeting. I'm wondering how best to determine volume size when I come across one at a pawn shop, etc if its not labeled as such?

I'm still going back and forth between dual 10's or single 12 sealed for my application. I see a few of these inclosures at different pawn shops and want to make sure that they will work for a given sub I might purchase. THeres gotta be a way to figure it out by taking a quick measurement. (although I suppose it all changes if its a "wedge" shape.)

Also, if I go with a 2-10 box....should there be 2 seperate compartments?

Tape measure.

Measure the exterior dimensions of the box, and subtract out the lost volume due to the material itself. Or, just write down the dimensions and plug it into a calculator like what's on http://www.the12volt.com.

Not quite following.

So lets say the box is a wedge measuring 32 x 12 x 8. How would you work that?

The volume calculator is cool...but I cant use it if I'm at the shop looking at something.

you would do lengthxwidthxheight and take that number and divide it by 1728 and thats ur cubic feet

take two two depth numbers and add them and divide by 2 to get the average number, and like stated above do LxWxH and then divide by 1728, and subtract 1.5inch from the external dimensions before you calculate the volume.
