Alpine SWX Series
10"
sealed box volume: 0.5-1.0 cubic feet
ported box volume: 0.8-1.5 cubic feet
12"
sealed box volume: 0.65-1.25 cubic feet
ported box volume: 1.0-2.0 cubic feet
When given a range as noted above, it is good to shoot for the middle of the specs. You get the tight bass and the boom this way. Also, don't forget to add the sub displacement into your calculations.

we can give you the recommended volume(as swez did above), but boxes are normally built to fit the car and change from one vehicle to the other.

"we can give you the recommended volume(as swez did above), but boxes are normally built to fit the car and change from one vehicle to the other". This is very true, the specs are in general b/c the vehicle itself will change the sound, it is known as Transfer Function. Also, when building a ported enclosure, you want to tune it correctly...you do not want to build an enclosure to the correct volme and put ports in it, you will end up with an enclosure that sounds like a sealed enclosure w/ holes in it. It is best to use the Thiele/Small parameters of the sub, take into accont the area you are placing the enclosure in, and how the enclosure will be aimed. It is some work and effort, but in the end you will be much happier w/ the sound.

That's an area that I've always been confused about. I still don't know how I should aim my subs (in a Dodge Dakota club cab).
I was thinking at an angle facing the middle of the truck, but then I'm worried about sound waves canceling.
Couldn't you amplify the sound by pointing the subs at eachother (not directly, but at an angle)?
