At the shallowest point you're looking at about 0.78 inches (2cm)

Almost an inch at the back

As for the grille height, between 0.75" on the windshield side and 1.2".
the speaker mount isn't flat which doesn't make measuring with a tape measure easy

oh and the speaker is 5 1/8 inch in diameter if that helps
Ask if you need anything else, the car is in the driveway with the speaker still off for a few days as I'm not using it due to the current situation
