Road Kill RKFR6 Speaker (Black)

Vibrations gone Mid base increased tinni treble decreased overall sound has improved and sounds like factory fit speakers if you have upgraded your speakers.

Seems to do a good job reducing resonance by sealing the speaker off from the rest of the door panel and instead directing it out towards the speaker hole in the trim. Even though my doors where fully sound deadened with butyl liner and CCF there was still a deep rattle present the really low tones. This seems to have gotten rid of that and further improve sound quality by directing sound where it should be. I didn’t quite understand the use in the second largest circle/foam and didn’t use it. Only issue is that the foam wasn’t wide enough to fit around the speaker bracket and I ripped one of the foam rings. For the other door I cut it to fit and applied a noise blocking foam over the separation.

Work well, and held up good over the years

Looks good quality and heard good things about it so can't wait to fit it.

Manera fácil y rápida de mejorar el sonido que sale de las bocinas del auto, aun así sean las de agencia ó si se tienen unas mejor le ayudan!

I bought these to help a set of adapter rings that were listed as fitting an 08 Subaru Outback, which they do sorta.... They bolt up fine, the screw pattern is there, but with a gap towards the front edge of the door. At first I used some Gorilla Tape and.some RTV, but that wasn't enough. Using the Road Kill foam rings made a huge difference. I removed the speaker from the ring and stuffed the smaller {cut down} foam ring around the inner perimeter of the adapter and stretched the bigger one around the outside circumference stuck to the door itself. A WORLD of difference! In the back, I used them more "traditionally" as a basket for the modified stock rings and again stretched around the outside circumference of the speaker ring mounted to the door. The sound out of my new 6.5 JVC speakers won't touch my old 6x9 3 ways, but they're far better with the Road Kill rings than without. They're much more focused and they sound more like they're "in the car" than before I installed them. I installed the speakers, drove around for a day, then turned around and ordered these rings. I should've bought them when I bought the speakers. Don't get me wrong, I still need an underseat subwoofer, but these will allow me to wait until it cools off to install one. 5 month update: The speakers have broken in properly (yes, that's a thing) and with the foam rings in place they sound pretty damn good in a car with no OEM sound deadening material in / on the doors. Obviously, having any sound deadening material would be leaps and bounds better, but these help. The subwoofer was a good choice too.
