Have 2 15 ma1500xl powered by a trx2000d amp. Right now they are in a sealed 4f cubic ft. box. Doesn't really sound good though. What should I put these in than. Never heard 15's in a vented box, what is the difference in sound?

how big do you think it should be and at what frequency should they be tuned around roughly?

3.5 cubic feet per sub/7 cubes all together. tuned to 40hz on paper, which once in your car will be around 32-35hz.
