i am looking at a set of focal access 165ca's they are 6.5" round and 66mm deep, will they fit without any mods to the door of a 2002 4dr blazer LS? or am i better off sticking to the JL evolution VR's which are 61.9mm depth?

 

they will fit in front doors with no modification, and you will need to put spacers on the backs doors, 3/8 of an inch too deep
