Front/back speaker size

Has anyone had experience with fitting non 4x6 inch speakers in the front ports of TJs? I want Focals, but they only make 5x7 inch versions.

The general consensus seems to be that you can take a 5.25 inch circular and fit it in, so I’m wondering if that would work better than the 5x7 elliptical.

As for the rear two hanging speakers in the factory bar, will 6.5s fit? I’ve also heard people say they fit even thought it’s meant for 5.25s.
