I've researched everywhere and found some inaccurate info. Speaker sizes for 07 sedan w/ Bose are as follows:
Front door: Tweeter: 3/4"--a 1" will fit with minor modification
Squawker: 3 1/2" Watch which brand/model you put in, as it is a tight fit. I replaced mine with JL Audio TR-350's (Not their top of line but fit). High end models will likely not fit without major modification.
Woofer: 10" Shallow Mount. I replaced with 6.5" w/ Neo magnet. Very narrow. If using a large mid-bass, may want to check w/ professionals to see if they'll fit. It's narrow.
Dash: 3 1/2"
Back Door: 6.5"
Subwoofer: 10" shallow mount.

Hope this helps. Pics of my front door adapting down to a 6.5" midrange.
