FAQs
Here are the steps to sound deaden your car floor to reduce noise by over 10 dB:
- Remove the carpet, upholstery and anything else on the floor.
- Clean the metal with denatured alcohol. If any rust is present, be sure to remove that first.
- Apply your sound deadener to the metal of the floor. Damplifier Pro goes on with a wooden hand roller at 60%+ coverage or Spectrum is applied in 2-3 1mm thick layers.
- Install Luxury Liner Pro MLV + Foam barrier on top of your sound deadener at 100% coverage for a sound blocking barrier.
- Replace the upholstery and carpet, and enjoy a quieter ride.

Sound deadening your car floor can reduce noise in the cabin by up to 30% on its own, depending on the current conditions. We always recommend pairing your deadener with a sound insulation like Luxury Liner Pro to block sound and insulate the car floor. Together, you can reduce noise in your cabin by 50% of more. If insulating your car floor is your primary goal, apply your sound deadening at 100% coverage to increase the car floors thermal resistance.
