About the Stinger RKFR6
From our tech experts at CEN
The Stinger RoadKill RKFR6 is a pair of three-piece foam ring kits for 6 and 6.5 inch (165mm) speakers. Each kit has a mounting gasket, a ring that sits around the outer edge of the speaker and a foam pad that goes behind it. Together they help couple an aftermarket speaker to a factory door opening.
Who it suits
Drivers fitting 6 or 6.5 inch door speakers who want more mid-bass and less rattle from the same speaker. Fitting smaller speakers? The RKFR5 covers 5 and 5.25 inch, and there is an 8 inch kit for larger drivers.
Our tech experts advise
The rings peel and stick, so no tools are needed beyond cleaning the surfaces. The rear pad stops reflections off the hard inner skin of the door, and the outer ring directs sound through the trim rather than into the door cavity. For the best result, pair them with door treatment. Get in touch if you want us to fit them.
