subthump stealth box?
The Infinity Perfect 10 is an ideal sub for the subthump box.
Big Tymer over on CZ28 volunteered to run WinISD for me, and here's the results for that sub with the Subthump box:
-10" Infinity Perfect
-375 watts RMS
-.7 cubic foot sealed enclosure
-This is out of car response (you can expect a lot more when put in a car).

Out of car response was measured partially because I have a convertible. Also, I still haven't installed this stuff. I'm kind of holding off until the weather gets hot, i.e. not the best track conditions.
