Stinger Roadkill RKFR6

A little overpriced

These fit well and adhered nicely. A little pricey for a bunch of foam.

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.

They do work

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.

Why didn’t I do this the first time?

I can’t believe I ever did an install without these. Amazing improvement in sound quality for a low price.

Makes the system sound so much better

I didn't know nor heard of FAST rings until a friend of mine Jim taught me about them. A must have

Major Difference

This set of rings makes all the difference in the world highly recommend

Roadkill 6" and 6.5" FAST Rings (RKFR6)

This was my first time buying and using the roadkill fast rings and I can honestly say it made a huge difference in quality and loudness. I will continue using this product for all my future installs well worth it and great price.

helpful product

Recommend!
Helps transfer sound from a speaker mounted behind door panels by sealing the gap between speaker & door panel. Really helps the increase midbass output & overall sound.

A must

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.

Roadkill 6" and 6.5" FAST Rings (RKFR6)

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.
