Description
Included in this kit
This bundle includes a Stinger RKFR6 Roadkill Fast Rings 6" & 6.5", and a JL Audio® C6 Car System 6.5" Two-way Component System (C6-650).
1x Stinger RKFR6 Roadkill Fast Rings 6" & 6.5" - (RKFR6)
Our 3-piece foam ring speaker enhancement system solves the problem of acoustically coupling aftermarket speakers to factory speaker openings. The RoadKill Fast Rings kit increases speaker output, improves the projection of the audio into the car cabin and reduces unwanted rear reflections that can degrade the sound.
3-piece Foam Ring System fits 6" & 6.5" Speakers
Features:
Reduce panel vibration
Increase mid-bass response
Enhanced audio output efficiency
Minimize destructive wave interference
Help prevent front and rear wave cancellation
Easy installation with peel & stick application
Maximize performance for speaker installations
Sold in pairs
3 Ring DNA
Gasket for speaker mounting to the baffle plate surface
Middle ring to mount around the outer edge of the speaker
Circular foam pad goes behind the speaker to absorb unwanted reflections on hard surfaces, such as inside a car door
