Used these on my install on my Yukon. Fit great and speakers sound a little better. Plus added protection from the elements.
Got this to keep the elements of my speakers in my RZR. Fit like a glove and sound like it improved the sound of speakers !

I cut a quarter size hole in the back of these to make a ported enclosure for my door speakers. I honestly can't hear a difference, but they are inexpensive and super easy to install, so why not.
Simple, inexpensive, effective
So far they seem to be a perfect addition to my system. I made several other changes at the same time so I can't make an apples/apples comparison about improving sound quality, but I do feel confident about the weatherproofing for the front door speakers. I have noted that the sound is a little less audible outside the vehicle. When installing you need to be gentle when pressing them into the speaker hole. They are a little soft and I made a small tear in one of them pushing on it.

These foam speaker baffles are excellent! They make any speaker sound much better! They also keep your speakers dry from rain run off that goes between your door. Very minimal mods to install.
