Our take on the Stinger Roadkill RKFR69 FAST Rings

You bought some nice 6"x9" speakers for your vehicle, so why not make sure they sound their best? Stinger's Roadkill FAST Rings RFKR69 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"x9" speakers for your vehicle, so why not make sure they sound their best? Stinger's Roadkill FAST Rings RFKR69 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.

  • kit includes two center pads, two inner rings, and two outer rings
  • designed for 6"x9" car speakers
  • foam baffles cut down on unwanted resonance
  • self-adhesive foam simplifies installation

Crutchfield Customer Review (What's this?)

They are definitely part of the sound treatment package I chose. I hope they don't soak up water in the door though. Sound improved and I'm sold on the concept. Thumbs up!

Pros: Sound improved

Crutchfield customer from Lenexa, KS on 12/23/2018

Crutchfield Customer Review (What's this?)

The adhesive on smaller pieces was not very good. I ended up discarding the smaller 6X9 pieces and saving the large 6X9 smaller pieces to repurpose them for something else. I doubt that I would putchse this product again.

Pros:

Cons:

Great for your speakers

Anthony Malave from Charlottesville, VA on 11/25/2018

Crutchfield Customer Review (What's this?)

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

Crutchfield Customer Review (What's this?)

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

Crutchfield Customer Review (What's this?)

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

Crutchfield Customer Review (What's this?)

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

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: 9"
  • Width: 6"
  • 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: 9-1/2"
    • Inner: 9"
  • Width:
    • Outer: 6-1/2"
    • Inner: 6"
  • 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: 10-1/2"
    • Inner: 9-1/2"
  • Width:
    • Outer: 7-1/2"
    • Inner: 6-1/2"
  • Depth: 2" (can be trimmed to fit)
