General Installation Directions:
    Mobile Solutions Foam F.A.S.T. Rings
  1. Separate the three pieces of Foam (101, 102, 103)
  2. Clean the back panel of the door, remove the backing paper from 103 and adhere directly behind the speaker to the outermost panel in the door. This will help absorb the rear wave and reduce panel vibration. (This step is optional as it is possible to absorb moisture)
  3. With a razor blade cut circumferentially 102 down to approximately 1/4”. Remove backing paper and adhere to mounting surface of speaker. This will decouple the speaker from its substrate and prevent front and rear wave cancellation.
  4. Using standard installation procedures wire and mount speaker.
  5. Clean around the outside edge of the speaker, remove the backing paper from 101 and adhere 101 directly around the speaker. Test fit panel for fitment. If needed trim 101 circumferentially until proper fitment is achieved. It should press tightly to the door panel. This will focus all the sound into the cabin, prevent panel vibration and destructive wave interference giving you noticeably improved speaker performance and less panel resonance.

Baffle Specifications

Baffle Material
This is the material that the speaker baffle is made of. Common materials include hard plastic and foam. Hard plastic baffles offer greater protection to the rear of the speaker because the material is much more sturdy. The foam baffles are easier to install and can create a more watertight seal.

A must

April 1, 2019

This is such an inexpensive product that it is a must when doing a pair of door speakers. It helps with getting the sound to your ears instead of sending it through the door cards.

Great product

Used these for a Toyota Sienna with Morel Maximo Components. Easy to install, did not install the large back piece on the door to avoid water absorption but used the inside and outside rings.

Roadkill 6" and 6.5" FAST Rings (RKFR6)

May 29, 2018

I wish there was a way for the big center pad to be the size of the entire circle as there are instances where you cannot place the intermediate ring in the door, and the window makes things even harder. Given the price though these do the trick and do it easily. They stick well to most any surface, including roadkill sound deadening.

Roadkill 6" and 6.5" FAST Rings (RKFR6)

May 16, 2018

What can one say about foam? The large circle that sticks to the door was just the right thickness to not hit the window when rolled down. I had to skip the outer rings on my install because of the way everything mounted, but the large hunk stuck to the roadkill mat I placed in the door and once pressed into place did not budge when tugged on. Sonic's price made the purchase and install a no brainer even if I didn't use all the rings.

They do work

April 19, 2018

All I can say is these things work as advertised. They aim the sound and cancel back waves. Thus increasing mid bass. This along with sound deadener in your doors will make a noticable difference. The only draw back is they are not waterproof.
