Wrong. 550 will get you the btl. purchased "at retail". Just because you dont have a brick and mortor store to walk into, does NOT mean fi is not "retail". DD is just priced high.
again with the names.. you are such a child. I am a fan of the team rf's, mach 5 stuff (more of a fan of mark than his products) andd fi is decent:) and there is no reason to be nice to idiots, liars and thiefs, and most brands are "me too" garbage. that answer your questions?
Don't worry Dave, you're still my favorite of the many druggy thiefs in the car audio world. Keep doin what you're doin, and I'm sure you'll keep scraping by:)
