About the Stinger Roadkill RKFR6 FAST Rings

Get better sound from your speakers

You bought some nice 6", 6-1/2", or 6-3/4" speakers for your vehicle, so why not make sure they sound their best? Stinger's Roadkill FAST Rings RKFR6 kit consists of six pieces of self-adhesive foam — two center pads, two inner rings, and two outer rings — which install on the speaker frame and behind the speaker, minimizing resonances and improving midbass response.

Get better sound from your speakers

You bought some nice 6", 6-1/2", or 6-3/4" speakers for your vehicle, so why not make sure they sound their best? Stinger's Roadkill FAST Rings RKFR6 kit consists of six pieces of self-adhesive foam — two center pads, two inner rings, and two outer rings — which install on the speaker frame and behind the speaker, minimizing resonances and improving midbass response.

1, 2, 3…better sound

The center pad mounts behind the speaker to absorb reflections from hard surfaces inside the car door or most other locations. The inner ring serves as a gasket for mounting the speaker to the metal surface. The outer ring mounts just outside the surround at the outer edge of the speaker, to couple the speaker to the door panel opening.

Stinger's Roadkill FAST Rings isolate the speaker from the mounting surface and the factory door panel to help eliminate unwanted vibration and noise from the door panels, while increasing midbass response. You'll have to trim FAST Rings for proper fit.

Product Research

Features

Overview: Each Fast Ring is three concentric foam circles, a center pad, an inner ring, and an outer ring. They mount around a speaker to improve sound quality. Typical mounting is in a door, but they can be used in almost any speaker location.

Center Pad: The center pad mounts to the inside of the outer door panel, directly behind the speaker. This pad absorbs much of the speaker's back wave, helping prevent interference with the front wave you want to listen to, and reduces vibration. Dimensions:

  • Diameter: 5-5/8"
  • Depth: 2" (can be trimmed to fit)

Inner Ring: The inner ring is sandwiched between the speaker and the mounting surface, providing a barrier to prevent low frequency (bass) cancellation. Dimensions:

  • Outer Diameter: 6-1/2"
  • Inner Diameter: 5-5/8"
  • Depth: 2" (typically trimmed to 1/4")

Outer Ring: The outer concentric ring mounts to the top of the speaker and is sandwiched between the speaker and door panel (or factory grille). This ring directs all the speaker output into the cabin, and acts as a barrier to interference from rear waves trapped inside the door panel. This ring also helps prevent the door panel from vibrating. Dimensions:

  • Outer Diameter: 7-1/2"
  • Inner Diameter: 6-1/2"
  • Depth: 2" (can be trimmed to fit)

Upgrade the sound on my Hertz aftermarket speakers! [ Logan  Dec 22, 2019 ]
A
good reviews and to get the most out of my sound system [ Christian  Dec 11, 2019 ]
A
This isolates the front and back sound waves from each other, resulting in better mid bass and less wasted acoustical energy in the door. [ Ivan  Nov 18, 2019 ]
A
Better sound funneling [ Brandon Scott  Nov 05, 2019 ]
A
To assist with the sound of my new speakers on an older design 1973 Ford Mustang. [ JEFF  Sep 27, 2019 ]

A
works for my installation [ Jeffrey  Aug 26, 2019 ]
A
Excellent product for containing and aiming the sound in the correct direction. Amazing how such a small product can make that big of a difference. [ Mitchel King  Aug 24, 2019 ]
A
For increasing mid-bass response, I have not found a better product. [ MICHAEL  May 15, 2019 ]
A
Wanted to try it out [ MARKUS  Mar 28, 2019 ]
A
Great ratings when I researched options to protect and enhance the sound from my speakers. [ Kevin  Mar 18, 2019 ]
A
Were recommended by a system designer on a user group I belong to. I was skeptical as to the benefit. As a test I installed it on one door and left it off the other. The output from the speaker with it installed was significantly higher than the one without. No question it helped boost the volume and clarity of the sound. Just bought a second set for my rear door speakers. No skeptical any more... [ Benjamin  Mar 03, 2019 ]
A
Based on conversation and recommendations of Francis. [ Gary  Feb 25, 2019 ]
A
Saw these used in a YouTube video by professional audio installers. I had just replaced the speakers in my own car and need something to insulate and direct sound better into the cabin of my vehicle. [ Daniel  Feb 24, 2019 ]
A
I have a 2007 Silverado extended cab w/t and the aftermarket speakers rattle in the rear doors. I figure I'll try this after Dynamat didn't completely eliminate the rattle. [ timothy  Feb 09, 2019 ]
A
Recommended by Francis from Tech Support [ Henry  Jan 23, 2019 ]
A
Recommended product to isolate sound coming through speaker. [ James  Jan 22, 2019 ]
A
These seemed to be a good deal [ Shane  Dec 21, 2018 ]
A
I was curious to see if they actually help with midbass. [ Adrian  Dec 06, 2018 ]
A
for better sound quality and sound isolation within within the door and sound direction into the cabin. [ Fernando  Dec 04, 2018 ]
A
To get maximum audio quality [ Lahiru  Nov 16, 2018 ]
A
If you're installing aftermarket speakers and you DON'T get FAST rings, you're missing out on a very easy way to improve the sound of your system. These direct the sound INTO your vehicle rather than having it bounce around/diffuse behind the door panels/cards. [ Charles  Nov 13, 2018 ]
A
Better sound [ Daniel  Oct 09, 2018 ]
A
only item like them [ Nathan  Oct 04, 2018 ]
A
My truck has big, open doors, and the midrange (component speakers) is very muddy. Hope this makes it a bit more crisp. [ Harry  Oct 01, 2018 ]
A
Recommend by your tech support and I was planning on buying here but when your tech support called me back in less than 10 minutes after my email. I was extremely impressed and you have just made life time customer. This is my first purchase here but it won't be my last. [ James112  Sep 28, 2018 ]
A
Louder mids [ Chais  Aug 13, 2018 ]
A
To enhance the sound of the new speakers I am installing in the doors of the car. [ James  Aug 01, 2018 ]
A
Aftermarket speakers have no seal. [ KUUHIAPO  Jul 23, 2018 ]
A
I probably won't need this entire kit...But, it looks like I will be using the outer rings for closing the gap between the speaker and the door panel for sound direction. It's too bad just the outer rings are not available separately. [ Paul  Jul 17, 2018 ]
A
recommended by installer [ Debra  Jul 03, 2018 ]
A
I purchased these to better sound response from my new aftermarket speakers. [ Stephen  May 07, 2018 ]
A

A
Used it before [ peter  Mar 27, 2018 ]

A
For aftermarket speaker install [ DUSTY  Feb 14, 2018 ]

Q
Are these open or closed cell foam?
[ Brad  Dec 22, 2019 ]
2 answers
A
If you mean is the foam open to the environment? Yes, it is. It's not sealed up. But it worked great!
[ Tiffany  Dec 23, 2019 ]
A
Open
[ Stephon  Dec 22, 2019 ]
Q
should I use the fast rings and the speaker baffles for the best results?
[ Jared  May 15, 2019 ]
1 answer
A
The speaker baffles won't work since they will impede The window from coming down. I even had to trim the foam back piece on the stinger rings.
[ Anthony  Jul 18, 2019 ]
