Box Plans For 2 12" Alpine Type R's

I've been searching for a long time and I'm kinda on a budget, but I really want to build a quality dual ported box for my 12" Alpine Type R subs. Please email me at if you have any blueprints or help on this. I want to do a ported box, but I need to figure out how to do it or I'll just have to do a sealed box.

Thanks for any help.
