OK i have 2 CVRs and there recommended ported enclosure is 1.75-2.25 per sub, my camaro i just messured and the width is 36inch, hight is 17 and depth is 12, and i got 2.12 cu. ft per chamber, and then i am gunna tune it to 32hz and my port diameter it 4inch and 12.64 long, you think it would sound pretty good and are my calculations right?
These are OD dimmensions (dont forget to subtract the center divider separating the two chambers as well as the outer ones too). Plus you will have to take out the port and driver displacement.
You would probably be looking at only 1.5 CF with your dimmensions.
