If you are taking up all the room in the back of the crx, you are making your boxes to big for spl. Generally on a kicker sub all you need is just over 1 cubic foot. Fire the woofers forward and aeroports directly out the back of the box (yes they will stickout) and then shorten the port to the desired freqency (likely to be around 55-60 hz). Anyway this box is like others have spoke of on here and it has proven itself many times. But its just for spl. I'm about to do my build on my crx and ill keep u posted with pics and tips.
