6.5" Foam Speaker Enhancer, Speaker Fast Ring Sponge Bass Blocker | 4P, Self Adhesive, Universal High Rebound for Car Door Speaker

This is the third set I have purchased for my vehicles. What I really like about these is is it soft rubbery foam not a stiff foam that doesn’t have a lot of give and it’s not like the flaky foam it’s the dense rubbery foam. But they are super easy to apply, but the best part is they allow your door panel to close without having to put any additional pressure in order to keep it closed. The full Ness of sound that is pumped into your vehicle is absolutely astonishing compared to stock applications instead of all that sound leaking into your door. It’s funnel directly into your interior cabin, great deal on a very reasonable product

Super secure. Make sure you line them up, because you won't be getting them off easily.

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,

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

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.

Great product, easy to install and fabricate if needed., Will definitely use again.

I was disappointed that my new aftermarket speakers sounded. Shrill and lacking midbass warmth. After research, I learned that speaker baffles may help. After installation, the sound is much more focused. The kick drum is much more present especially the "knock" around the 100HZ-200HZ area. The warm overall sounds fuller and I can hear more music in the noisy traffic than before the install. I'm astonished how a simple foam ring can make the music that much better. Night and day difference :)

What I like most about this is the fact that it come round but is nice and flexible for me to make 6x9 rings out of as well. With 4 6.5” circles I can make two 6x9 rings. I’ve had trouble finding these rings for 6x9’s so this was my best option. But it actually worked out very well. These are very easy to make adjustments to. I print a 6x9 shape with my vinyl printer and attach that to the front to hold the tape then peel the adhesive off the back and stick em to the frame and lay the door panel on top. Perfect

These are probably best value foam rings out there as it’s affordable and closed cell foam.

Exactly what I was looking for, avent use the adhesive yet, but it’s 3M and other reviews sais it’s good.

Too thick to fit between speakers and door panel and also rear deck. I took too long installing to return now. Waste of money.
