You can get 6x9s in,it just isn't pretty.
I had a front and rear set of 6x9 4-way 280w Kenwoods in my Mystique. Man did that ever sound awesome. 6x8s are good anyways,they're just generally harder to find,since 6x9s are much more common. Currently in my car I have Pioneer 6x8s in the front (from Wal mart w00t) and Pioneer 6x9s in the back.
