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? This FAST Rings F.A.S.T. 6x9 kit consists of three pieces of self-adhesive foam — a center pad, an inner ring, and an outer ring — 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.

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.

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, providing a barrier 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: 11"
    • Inner: 9-1/2"
  • Width:
    • Outer: 8"
    • Inner: 6-1/2"
  • Depth: 2" (can be trimmed to fit)

Q
Can the 6x9 fast rings be forced to fit 4x10 ?

A
The fast ring can be cut to fit. With my door design, I had to cut and customize a bit to fit. As long as your keeping the basic principle and operation design intact, they should still do their job. Even cutting and modifying, I was extremely impressed with the difference in midbass quality I got out of them.
