I know that most of your sound comes from the front speakers but can you fit a bigger speaker 6.5 speaker in the back shelf in a 2009 sedan?

I wouldnt make the rear sound better than the front sound, except for deeper tones which are less directional.

If you already have 6.5s in the front then adding them to the back too makes perfect sense.

I just have the 4' in the front but I have focal 6.5 and type r 6.5 just laying around

I plan on fiberglassing some 6.5 speaker pods for my CTS 6.5" speakers this weekend. The pods will be up against the lower front portion of the doors, but free sitting on the rug (although when the door is closed they will be held in place by a strap in the door jamb) so they will have to be moved to get my feet out. Not a great solution but they will have a few advantages over kick panel or door enclosures:

No modification of OEM panels.
No loss of foot room on the left foot rest (I drive an automatic) if mounted in kick panels.
No added weight to the doors wearing out the hinges (my drivers have 30 oz magnets)

I will try to take pics and post them as I build.
