Stinger Roadkill RKFR69 FAST Rings
Joe from Palm Harbor, FL on 4/13/2025
I had looked at other kits from other venders before I bought these from Crutchfield. Crutchfield's kit seemed more complete. And because I have purchased other items from Crutchfield I knew there fulfilment was fast

Must Have
Cesar from Fort Worth, TX on 11/25/2024
This set of fast rings is a must on every installation even a cheap set of speakers sounds lots better with the appropriate installation gear than a very expensive set without it.
Pros: Price point Simple installation process Adhesive works really good
Cons: Depending on application sometimes requires trimming some in order for it not to end up on the speaker surrounding materials

Expensive
David from Sacramento, CA on 11/12/2024
For the cost they should be easier to separate. Also the middle one should be perforated to half thickness because most cars probably don't have room for full thickness. Also, for the cost should precut ring for speaker seal, that would not be very thick for anyone. But they do the job I guess, hopefully they work as I can't tell the difference.
Pros: Stick well
Cons: Expensive for what you really get

Stinger Roadkill RKFR69 FAST Rings
Russell from Providence, RI on 9/16/2024
They work as advertised, but it is difficult to separate the rings without damaging them. The perforations are spaced too far apart in several places - I had almost an inch of connected foam to cut through in order to get the rings apart. The backing paper peels off easily when removing the middle ring, which can lead to a sticky situation.

Well worth it
Edward from Pennsburg, PA on 7/5/2024
Fit perfectly in the door and around the speaker. You can tell it sealed against the door and sends all the music through the speaker grill versus it flooding into the door

Gets the job done!
Jeremy from Wapwallopen, PA on 5/21/2024
Excellent product. Durable material, adhesive backing is very strong, easy to use. Out of two sets I ordered, one was not thoroughly cut, requiring cutting and shaping on my part. If not for the uncut ring, I would have given 5 stars. I Highly recommend this product.
Pros: Everything about this product is a pro!
Cons: No cons unless you run into improper factory cuts as I did.

Just get them
John from Westwood, NJ on 9/23/2022
This is just something that I didn't know I needed until I started watching YouTube install videos. How much difference does it make? Who knows. But I felt like if I was going to do this, a few extra bucks to guarantee the best outcome was worth it.
Pros: Creates a tight seal between speaker and door panel.
Cons: The adhesive is kind of weak.

Was skeptical - but now sold on it!
Thomas from Yukon, OK on 9/13/2022
I was skeptical about these rings - but when I actually installed them, I was impressed with the results. Definitely provides tighter, more natural sound quality. Couldn't install the backer right behind the speaker due to the side impact brace in the door - but I did install offset and still notice cleaner, tighter sound and even a little less road noise. Great material - and easily cut to customize your install needs. Very happy with this product. EASY install!
Pros: Easy, tailored install Cleaner sound quality Less road noise!
Cons: Can't always put them exactly where you want Still a little skeptical about long-term adhesive strength

helps but expensive for foam
Weston from Salt Lake City, UT on 9/1/2022
I'm sure this is working for the speakers that had room for them. I couldn't use all of them due to lack of space but, I used parts of the foam. I deducted 2 stars because this is a ridiculous price for foam.
Pros: helps with vibrational sound loss in doors
Cons: Price

Worth the $!
Brad from Brandon, MS on 8/22/2022
Improves overall sound and makes everything sound more focused. The thin ring that fits on the back of the speaker tears very easily though. Would definitely recommend.
Pros: Improves sound
Cons: Rings tear easily

Kenneth from PIERCE, CO on 7/20/2022
First time using, easy to trim to make fit. I believe it made a difference in the sound, especially in the door speakers. No more buzz or rattle, took care of a lot of the hollow sound from within the door.

Poor glue quality and it is barely applied and present on the product.
Cristian from Belle Chasse, LA on 6/27/2022
CON: The glue on these rings is sparengly applied and it does not adhere to the foam itself. Could not use the product at all.
Pros: Dense open foam and with plenty of elasticity to not rip when handled.
Cons: Glue does not adhere to the product itself, yet alone on the door/speaker. Barely any glue applied on the open foam product to gegin with.

Would like to give them five stars but can't
Randy from Argyle, TX on 2/14/2022
Would like to give them five stars but I can't I think 3 stars are a little much to, but the middle ring is so thin it ripped in several places just trying to get them separated so much for the back ring around the speakers not too happy about that maybe should have given two stars.
Pros: The inner and outer rings are good and nice and thick
Cons: But the middle ring is so thin it ripped in several places just trying to get them separated :( so much for the back ring around the speakers

Works well would buy again
Crutchfield customer from Hampstead, NC on 1/11/2021
The fast rings help keep the sound 8n the car instead of bouncing around inside the door. They stick on easy and it is easy to cut/modify them.
Pros: Easy install and funnels sound
Cons: A little cumbersome to pull the 3 rings apart. Sticky paper backing falls off easily on outer rings when separating.

Stinger Roadkill RKFR69 FAST Rings
Crutchfield customer from Corpus Christi, TX on 10/24/2020
After installing the 6 1/2" set in the front doors I opened the 6*9 set to install them in the rear doors only to find that the 3 sections of the fast rings were not cut properly. The rings almost tore as i tried to separate them. I had to use a large knife in order to separate the 3 rings in order to install. Additionally, the paper that covering the adhesive so well on the 6 1/2" set was almost completely off of this set. Beyond that they were acceptable.

Brah dont
Crutchfield customer from Waipahu, HI on 7/13/2020
Thought I needed it. I didn't. Way too thick. Save your money. My friend thinks it would make a good pillow. I'm going to get teased about it when having difficulty with projects. If it don't work you can use the foam on it. Waste of money
Pros: Super sticky backing
Cons: Don't need it. Don't buy it.

Fast Rings - a no brainer! Must have.
Crutchfield customer from Waxhaw, NC on 5/27/2020
These were excellent. I coupled these with some foam speaker pods and the door speakers never sounded so good. I was about to add a Amp to get some more sound until I used these foam speaker rings. Now more sound makes it into the cockpit than before.
Pros: Relatively cheap and easy to install
Cons: None so far

Good idea not enough room
Crutchfield customer from Nashville, TN on 7/12/2019
Thought this was a great idea, speakers were easy to install however i had to tear it all back out and remove this product. There is not enough room when the window rolls down and this padding need up in a wad behind the window not allowing it to go up/down.
Pros: Easy to install, cones on speakers fit great
Cons: Too thick for windows to roll down and ends up sticking to the window on the way down. Just don't put the block behind the speakers. It will not stay

Pros: They are very easy to install
Cons: You will have to cut them down to get them to fit properly

Great for your speakers
Anthony Malave from Charlottesville, VA on 11/25/2018
Big improvement in bass response and absorbing vibrations around the door panel. The fast rings are a really great and quick way to get the full potential out of your speakers especially when in your car. I did a similar review on the 6.5 but the 6 x 9 were also great. You can modify also to fit in most spots for example to get it to fit behind the window track, or rear deck panel.
Pros:
Cons:

Does what it says, tricky install on some vehicles
wyatt from Livingston, TX on 11/25/2018
When used properly these do exactly what they say they will. They improve sound quality to an audible degree. However check your application REALLY well before you drop coin. Some vehicles just aren't made for this and you will either have to become REALLY creative, or scrap the whole project. But if you can use them they will not let you down.
Pros: Seriously improves sound
Cons: fitment issues on some vehicles

Useless Kit
TC from Corpus Christi, TX on 5/27/2018
Most of this kit is useless. The largest backing piece is useless if you have windows that track behind the speaker which most vehicles do. Waste of money. Usually excellent suggestions from sales, this one I regret buying.
Pros: Foam for between speaker and bracket ok
Cons: 99% of this kit is useless Unusable large back piece which is most of the kit

Works
Matthew from Richmond, VA on 4/27/2018
Didn't quite fit behind the speaker because the window rolls down on and there is a reinforcement bar in the door, but easy to trim down. I think it sounds abit better than without and easy to add. Put in a toyota sienna 2006 with jl c1 690
Pros: Easy application
Cons: Can't place specific location some parts of vehicle
