The Stinger RKFR5 is a 3‑piece foam ring enhancement system engineered to acoustically seal aftermarket 5″ and 5.25″ speakers into factory speaker openings. By improving coupling, it increases mid‑bass response, reduces rear reflections, and minimizes wave cancellation for cleaner, richer sound inside the vehicle.
Each kit includes two sets of foam rings (one per speaker) for easy, peel‑and‑stick installation. Ideal for upgrading factory speaker systems with minimal effort and cost, the RKFR5 kit helps your new speakers perform at their true potential without modifying the door or speaker mounting location.
Note: Always measure speaker diameter and mounting depth before purchase to ensure fitment.
