Those 6.5” look pretty good installed. The edges are past the door grill but not that much. I measured it would be about .5” and wondered if it would affect it and vibrate the plastic.This is a 6.5 inch Focal speaker installed on another 400 in my area. The installer sent me the pics to show me how it would look. They did have to trim the existing hole to get it to fit of course. And build a custom fabricated fiberglass speaker mounting plate to allow upgraded 6.5” speaker size.
