  • Do you ever drive on the highway at 65 - 70 miles per hour and then exit. When you come to a stop light what is the first thing you do? The first thing you do is turn the radio down because it is too loud! The noise in your vehicle while driving on the highway forced you to turn up the volume so you could hear it over the noise. Everyone does it every day! You don't have to. HushMat installed in your car, truck, SUV or wagon will lower the noise floor by over 10 Db which in turns allows the full amplified sound to flow throughout the interior. You will almost certainly gain of 2Db of quality sound from your stock stereo - even more on higher quality aftermarket systems.
  • D-Sport magazine performed an independent study and found that HushMat increased the stock stereo by 7.9 Db at 100 Hz frequency!!!! Incredible results from HushMat.
  • You don't have to settle for bad / low quality sound. Another question: Which sounds better? A nice wooden home audio speaker enclosure or your car door? The home speaker is built into a solid wooden sealed enclosure. The car is a thin, vibrating piece of metal with a bunch of holes and hardware attached to it. By treating the car door with HushMat you are making it a solid sealed enclosure just like the home.
