4PCS Speaker Foam Enhancer,6.5" Speaker Foam Rings for Enhancing Stereo Sound in Car Speakers,Universal Self-Adhesive Speaker Gasket Car Accessories for Car,Truck,SUV

Replaced all 4 of my door speakers in my 11 STI.I used this on the door and the face of the speaker.They work really well and stick pretty good.I did have to trim to fit my 6.5" speakers.

Its exactly what it says it is. Not much to say other than you are getting what is advertised.

Too thick but cut it and be one with life

Works as they should. Easy to install and definitely improves the sound of my upgraded speakers

Put these on the front 2 speakers of my 2008 Toyota Corolla LE. They fit great and installation was pretty straight forward. As far as effects, I could instantly tell the difference in smooth vibration and bass movement after I put them in. Definitely worth the price and adds a noticeable benefit.

Worked great for installing new speakers in my car. No rattling. Great price and good quality.

Have to cut to make it fit a 6.5. But does direct sound very well

These are phenomenal and much better than those open cell foam speaker rings that don't do anything. Only think to keep in mind is that these won't fit around anything larger than a 6.5 in speaker.
