I have researched this topic a lot on a number of forums and the consensus seems to be that 6.5" will be ok in the front of coupes but for sedans you need to stick to the factory size of 5.25". The reason being the depth of the door is different. For the rear, 6.5" should be ok for both coupe and sedan.
front for the sedans are 5-1/4"..........BUT its better to get a shop to CUSTOM fit 6-1/2's in the front..........it can be done and has been by others on this forum........for the rear, just go with coax's or somethin..........your fronts more important and get a nice amp to power it too 4-channel:thumbup:
