Pioneer 6.75" fitment question.

[95ZJ]

Would they fit in a 6.5" opening? I already have to deal with the 6x8 hole my truck comes with, I just want to know if they'll fit my adapter because I'm asking for these for Christmas.

[WKD TC]

what are you trying to put it into? and which pioneers?

[sqhertz]

iirc , they fit into most GM vehicles.
if not , do a little cutting if you already have them.

I don't have them and they're going into a 2002 Ford F-150 reg cab. I'm doing those up front, and some Pioneer Coaxes in the back.
