These worked out great for my application - the speakers I was installing had just a little interference with door panel, the baffle was a great gasket to use to give a good, even seal. My previous upgraded speakers did not have any kind of rain shield and the output tabs had rusted off from where they attached to the spider so I want to make sure I did not make that mistake with my new speakers. I used JL C2-650x and they fit perfectly in the shallow depth ones - there actually is room to fit the regular length and that would be a bit more optimal most likely. They appear to be waterproof, I put water in one and it did not seep in at all. My only concern is that the speaker might get hot without room to breathe - I may cutout some of the bottom to take care of that. No idea if they change the sound but my speakers sound good so I am happy.
Could not use these

No issue with the baffles themselves, other than there was no way to use them. Why did Crutchfield suggest them if they wouldn't fit my car? Now its more expensive to return them than to keep them.

Was recommended to use these for front door Rockford Fosgate 6.5" component woofers. I'm not an audio expert enough to understand why they are not used in the stock speakers and why it was suggested for the replacements. As suggested, I did cut out a 1" diameter hole out the back "to let the speaker breathe". I did not do a with and without comparison, but am trusting they will better protect my new speakers and prevent any artifacts that could occur without them. Not sure why they were not recommended for the rear door 6.5" speakers.
Protection where you need it.

These do exactly what you would expect. Perfect for isolating the speakers from the elements. Exposure to moisture in the door made to old speakers brittle and ultimately fail. I cut a small hole in the bottom for wires, otherwise installation was plug and play. Yes, they cut the bass, but look up baffle in the dictionary before you purchase, ok? Don't complain because they cut sound since that is what a baffle is designed for. If you want full sound (and bass) but still need to shelter your speakers, build a custom fiberglass (or other non-absorbant material) enclosure.

have used these in the past - they keep door speakers clean, also get better sound from speakers. No need to worry about rusted speakers with these.
