My buddy gave me 2 12" ultimate subs. They are only 150 watts each. and a 700 watt Ultimate amp. Anyway, i had 2 10" Jensens in a ported box tuned to 35 hertz and it sounded real good. How many square feet should i build the box for the 12's and should i seal it or port it. If ported, at what frequency would make the subs sound better at low frequency?

We can't really know that without seeing the specs for those subs, sealed is the safest bet if you can't find the specs but ported will be louder.
