I came across this online today and I've been looking for box plans. This let me put all of my driver specs and the size that I need the box, the cu ft for the box and the frequency for the box. I am getting a Fi BL15 and I'm thinking 3.8 cu ft and 32 hz. This is the box that the site gave me. I am a little concerned about sound quality. I listen to a lot of rock and rap. My main concern is that I want my car to really shake, and I want to be able to FEEL the bass.
Would that be a good box?
The only other thing I would do is extend the top and bottom by .75 for some over lap and use double thickness on the front. What do you guys think?
