6.5" Foam Speaker Enhancer, AngleKai 4Pcs Self Adhesive Speaker Fast Rings, Universal High Rebound Sponge Bass Blocker Kit for Car Door Speaker Foam Rings

These actually make a noticeable difference. I have installed them in my 05 Toyota Sequoia and my 2017 Mazda six. The clarity of the base is remarkably improved. The sound goes into the car instead of behind the door panel. Worth the expense when doing your own install

Installed today. Great packaging and adhesion on rings. Immediately noticed a difference. Would definitely recommend. Especially for those with older cars. Mine is a 06” Accord. Great buy

I combined these with Amazon-brand sound deadening and it worked wonders for the rattling and sound projection issues I was having on my most recent sound system install. Worth the money.

They work well. You might need to put a little extra glue on the backside of speaker as Aftermarket speakers, like I put in my car, put their stickers on the back side of the speaker. So not the fault of this product. Just be mindful to start with a clean face (sticker free) where these will be placed. have a few extra pieces of double sided tape JIC you put it over the stickers

Nice strong foamand it is very sticky to good quality.

Pretty decent quality product I found the outer rings only work on two of the four doors on my 4Runner. The rings are pretty thick but they do compress easily. Just make sure you’re going to able to fit them. Most factory inside panels have a plastic ring that sticks out already so your available space may vary. I definitely used the inner circle on all the doors behind the speakers. Overall pretty good product for the cost.

Since I had to replace the speaker mounts I installed these. Noticeable difference in sound directed into the can of the truck vs the dead air space in the door panel

I bought these for my Ford Explorer Limited 2013, the rear speakers are 6.5 and for whatever reason I really couldn't hear them especially after upgrading them to components. Not only that, the freaking door rattling when the bass hit drove me crazy.I saw these and took a risk, what's the worst that can happen with the price I'm paying for these?Well, what ended up happening is more focused sound, the bass was accurate, I was now able to hear the rear speakers from the front seat, the music sounded more fulfilling, and that freaking rattling was gone.This truly does make a difference in the sound direction, the isolation of the sound, and enhances the sound by controlling all of the lost sound.These were by far an amazing surprise of an upgrade.With that said, I have my doors sound proofed with sound deadening material, so I am not sure what kind of major difference this will make to a non sound deadening car, but I'm more than sure it will indeed be a difference for sure.I recommend these completely,
