I am trying to upgrade the dash speakers in my "new" 84GN with a decent quality and easy drop-in 3.5" 4 ohm speaker. I don't have speakers in the door . As you know, the tweeter can't exceed the top of the cone...it requires a totally flush mounted speaker. Crutchfield has nothing according to their techs. I've spoken with a few car audio shops...no luck. I'm hoping find to find something quality (maybe even discontinued) that will fit. Anyone have any info?
