Ok, so I did a lot of searching. I know the front speakers are 6.3" and the rears are like 5.5...HOWEVER:

What kind of mounting depth am I looking at for the rear speakers? I talked to some tech advisors at Crutchfield, and they said the mount depth for the front is 3.3" and the rear is 4 point something. But they ALSO said that our door panels only allow for very shallow speakers, so that coaxials in the rear that are 6.5" are basically a no go, and I have only a few options that only allow for components.

In the front they said I'd have to go with 5 1/4" components but I know for a fact that people are running 6.5" components. How did ya'll sidestep the height issue of the speakers hitting the factory grilles (door panel grilles)?

 

I'm running 6 1/2 components in the front and 6 1/2 two-ways in the back. I install all them using 3/4 inch baffles that I made using MDF. For the rear speakers you will have tons of room, the rear quarter panels are pretty hollow. Take out the back rear panel and take a look.

I have Infinity 6010cs components in front and Infinity 652.7i in the back.

 

thanks!
