Good Installation Practices - Door Speakers

Hi everyone, going to be installing some new door speakers in my 24 Ranger in a few weeks. Going with 6x9 for the fronts and 6.5" for the rears. While doing the installation, what are some best-practices for ensuring a good install and eliminating rattles?

A couple things I'm going to be doing: Foam rings around speaker face to seal against inside of door cards, felt tape on wiring connections, dynamat on the door itself..

Are there any other things I should be doing? Felt tape between the plastic speaker mounting rings and the door? Silicon or adhesive on the screws so they don't backout?

Thanks!
