The good thing about 6x9's is their increased (woofer) cone area moves more air and thus can produce more sound than would a 6.5 with the same excursion.
The bad news is no one really makes high quality 6x9's. So you get inferior woofers, tweeters, XO's, ect...More bad news, they're deep and the extra cone area weighs more and thus transmits more energy into their mounting surface. So you have to add more sound deadening to your door, if you can even get it to fit.
