Get better sound from your speakers

You bought some nice 5"x7" or 6"x8" speakers for your vehicle, so why not make sure they sound their best? Stinger's Roadkill FAST Rings RFKR5 kit consists of six pieces — 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.

Seems to work well, but did require some trimming to fit behind window track of F-150.

Pros: Easy to use. Increases mid-bass response.

Cons: Minor trimming required.

Product Research

Features

Overview: Each Fast Ring is three concentric foam ovals, 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:

  • Length: 6-7/8"
  • Width: 5"
  • Depth: 2" (can be trimmed to fit)

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

  • Length:
    • Outer: 7-5/8"
    • Inner: 6-7/8"
  • Width:
    • Outer: 5-1/2"
    • Inner: 5"
  • Depth: 2" (typically trimmed to 1/4")

Outer Ring: The outer ring mounts to the top of the speaker and is sandwiched between the speaker and door panel. 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:

  • Length:
    • Outer: 8-3/4"
    • Inner: 7-5/8"
  • Width:
    • Outer: 6-1/2"
    • Inner: 5-1/2"
  • Depth: 2" (can be trimmed to fit)

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I have a ford ranger the rear speakers where mounted has a huge cavitiy. I don't think I'm getting everything out of the speakers. Along with reviews I've read this should help, we'll see. [ Matthew  Jul 11, 2019 ]

After doing reasearch these dampers looked like the best choice on the market! [ Daniel  Jun 24, 2019 ]

Improve the sound quality of the speakers [ Nicholas  Jan 17, 2019 ]

highly recommended by anthony [ Joel  Dec 10, 2018 ]
A
I did some research and compared this item to the other baffles that were in stock. From what i read from other reviews on other sites and videos these were a lot more effective at what they were made to do. The other baffles had a lot of confusion about install and how to use them. These items had better instructions and more video installs on youtube to help me decide. [ Russell  Sep 30, 2018 ]

A
Yes. It comes with two of each piece (center pads, inner rings, outer rings) for use with a pair of speakers. I hope that helps. My Bio: https://www.crutchfield.com/bio/Ryan
