OK, I am going to rebuild my box to custom fit my trunk. I also have a theory I want to try in building my box. See, I want to have my subs faced in an upside down position, facing the floor. Now, I want to mount supports to the box to hold it up in the air. I want a hard, sound reflecting material right benieth the subs. My idea of how the sound waves would be distributed is shown in the attached picture. What I want to know is, has anyone tried this before? Even so, how do you guys think this would work IF it were set up CORRECTLY?
