You have a mustang I read? I had a 12" btl in a 95 mustang and went through 6 or so different boxes and different port combos. I took one box and by just making the port area smaller tuned it down to 27hz and picked up a little over 2db. It liked a much larger box with less port area. IIRC it was something like 4.5 cubes and for a 12 it moved alot of air and would meter a 145 at the dash, but when it was tuned higher with more port area I could only get a 143. its allll in the box.</p></blockquote><p></p>
