I would build it an see how it sounds. I would be intrested to know how one of those do in a 6th order or 4th. I doubt anyone here's done that with obsidian 18s yet so you might be on your own on this one lol. Post pics if you go forward bro!

I plan on it im surprised that I might be the first on here I have a dd1 so I no that it will help since you cant hear distortion in a BP box all I can say that it will be a bitch to install in a cavalier all I can say its trial and error and thnx I hope it goes well

Those subs vastly favor 4th orders over 6ths. Just saying if it was me, I'd do a 4th and not give the 6th a second thought..and I love 6ths have a walled one right now lol.
