These are a direct fit in the factory 3.5 bracket, with Minor trimming to remove the factory speaker, as it's glued in. They are very good, but don't have the best off axis response, so there might be better. That said, this is what I have in my car now.

Edit, in the picture is a test fit, I did screw them down before finishing
