I think the cuFt is about .25
there are alot of angles to cut off of the dimensions listed above.
I thought it was too punchy, too much mid bass for my tastes - but I was using a cheap sub (spark-o-matic leftover from my chevette) that I found in the back of my garage. Also, the amp had no crossover adjustments.... so I am looking fo a sub to meet the cuFt and an amp to match at this point.
the box has been removed for now, but I plan on using it when I get components I like. Its a nicely built box and a snug fit. Does not intefere with any foot room for the passenger.
