The fastbacks fit only 4x6 all the way around. Unless you make your own bracket. I made a preliminary template using plexiglass so I could see where everything was going to go and how it would fit, then made one with a thin sheet of wood, and some dynamat extreme on both sides, then put a 6.5" speaker in there. I plan on doing the same with the rear with 6"x9" speakers, well minus the plexi. BTW plexi rattles like a mofo. The placement of the 6.5's if you're going to use the Infinity Kappa 63.5i's should be as far away from the driver and passenger on that custom made bracket as possible, otherwise you'll encounter the window hitting the top of your speaker and won't crank down all the way.
