I've had those 6X9's. They are damn good. But personally, I like these better.. The bass is less muddy when cranked and they sparkle.

As for door speakers. Polk makes good ones. The 6.5's I had in my door lasted for 10 months before I took them out, and they were amped and thrashed daily. Still work, just decided to upgrade to components instead.
