I have 2008 Dodge Ram 2500HD Quad Cab with standard radio and 4 speaker setup. I want to upgrade stereo and speakers. Does anybody know what size speakers will fit in each of the doors. I want to do components in the front doors and coaxil in rear, but I don't know what size I can go on each door. Any help would be much appreaciated.

 

stock sizes are
rear doors - 5 1/4
front doors - 6x9

you can install 6 1/2 in the rear doors though
