Damplifier Pro is a foam shield mat that you put under the floor mat of the car. You basically install it under the floor mat in front seats. What this Damplifier Pro mat does is that it insulates or soaks up the sound coming from the tires under the car. It insulates all the vibrations and sounds a lot making the interior of the car more soundproof.

 

 

Damplifier Pro sound dampening mats are made up of using butyl rubber combined with a foil constraint layer on the side. There is an adhesive on the other side to help with the easy installation. You don’t require a specialist to install this mat. You can easily install it by yourself without any professional help.

2. Combine the Soundproofing floor mat with a Reflective Insulation for more effective car soundproofing

 

Only installing a soundproofing mat is not that effective honestly. You need to combine it with good reflective insulation for effectively soundproof and block outside noise. Trust me this works very well.

For this, you need to install a Mass Loaded Vinyl as a buffer between the Soundproofing Mat and Car’s floor mat. This will block 100% of the noise that is coming from below from the wheels and suspensions. Mass Loaded Vinyl is an excellent soundproofing material.

The best Reflective Insulation is the Luxury Liner Pro. It is the best option that Is available in the market. An additional advantage with this reflective insulation is it will keep the car warmer in the winters.

 

 

How to install Reflective Insulation in your car?

  1. The reflective insulation should be installed on the soundproofing floor mat.
  2. Place the reflective insulation above the soundproofing floor mat. These both are meant to work in conjunction to eliminate all the exterior noise to enter inside the car.
  3. Place the car’s floor mat above the reflective insulation.
