I'm going to go out on a limb and say that the majority of Bass, I Love You is below 35Hz. Playing below box tuning will cause unloading, so essentially the woofer would behave as if it would free-air. You don't want that...
Good rims? BBS, Volk (or anything made by RAYS), Enkei, Rotiform, SSR
Do yourself a favor...please don't get XXR or Rota or any of that cast knockoff stuff
I was actually on the phone with DD last year sometime, asking this very question. THEY seemed to be all right with the idea, but it also may have been out of an effort to sell me the woofer.
If you're as big of a fan of the E60 M5 as I am, you'll probably love the hell out of the one in this video. $3400 exhaust that really makes it sound like it should.
Talk about underrated. And I heard these go for $1799 retail? Don't quote me on that. If I had a little more money (and the need for that power) I wouldn't hesitate.
