Fast Rings

enhance the sound in your vehicle using fast rings

FAST solves the problem of acoustically coupling aftermarket speakers to factory speaker openings.  It’s a laser cut foam product with industrial-grade, peel away adhesive backing.

The rings separate into three pieces.  The first FAST Ring is a dedicated gasket for speaker mounting to the baffle plate surface. The second ring mounts around the outer edge of the speaker, just past the surround.  The third circular foam pad goes behind the speaker to absorb unwanted reflections on hard surfaces, such as inside a car door.

By using the 3-ring approach the kit improves the projection of the audio into the car cabin and reduces unwanted rear reflections that can degrade the sound.


  • Increase Mid Bass
  • Reduce Panel Vibration
  • Reduce destructive wave interference
  • Help prevent front and rear wave cancelation
  • Focus all your sound into the cabin


These are available to purchase to fit speaker sizes 6.5″, 8″, 5.25″, 5×7 & 6×9 and start at £29.99
