Car Door Speaker Fast Rings Foam Bass Blockers, Car Universal Foam Speaker Enhancer System Kit for 6.5" Speaker 4 Pcs - Self Adhesive

Ordered these as they were a lot cheaper than other products and most reviews said they were real closed cell foam. Confirmed they don't hold water. I went to install them and they are too small to go around 6.5" speakers. I ended up cutting them and leaving a gap at the bottom of the speaker. 3M tape layer is perfect, I cleaned the door panel with alcohol and the rings are stuck on very secure. If they were a little more rigid and about 2" bigger circumference, they would be perfect. The center foam is not usable on my car, if i was to use it behind the speaker, it would interfere with the window. As they stand, still worth it for the price, but I will look somewhere else for the other 2 doors.

Good

Great product. Put a whole new system in my car and used this on every door speaker.

These worked very well for installing new speakers on the door of my 2020 Telluride. I used these on both front and back door speakers, super easy to use!

These closed cell foam would be better for sealing than directing air. Tough as nails to trim. Do yourself a favor. Spend the extra few dollars on Stinger brand fast rings.
