Couple of box questions, help please

[Afboy143]

I have 2 12" Type E's alpine subs and i wanna make a custom sealed enclosure for it. I searched the forum and i cant find the post about it, but i remember seein it. it was about making the raised lettering under the capet of alpine sticking up. How do you do that again? Also how can i find out how much space inside the box the alpine subs will take up? I wanna make the box exactly 1.25 airspace for each sub. Thanks guys!

i'd say keep it right around 1cube for type e's if your keeping it sealed. should keep it nice and tight
