Yup, I cut my front doors to fit the 6.5"s in there, then attached a 6x9 to 6.5 conversion template to the metal, and the speaker to the template. The template is 1/8" thick plastic and also serves the purpose of reinforcing the inner sheet metal where the ridges were cut away. Worked out perfectly. Also as SSQATCH said, make sure the saw blade and drill bits aren't too long. Good luck.
