4 inch door speakers
Sorry long week, fell asleep last night. The speakers I installed had a depth of 1 7/8" and were 4" in diameter. Attached are pictures of the stock speakers. Look closely and you can see I took pictures of inner and outer ring as well as top shots.
Hope that will give some guidance. Sorry I never took pictures of original door installs as I was focusing on the project and a little nervous. Actually pretty easy as long as you use a plastic or nylon pry tool set as to not chip the wood inserts. And never never tear those darn vapor barriers. Lol.
