Review on 🚗 Enhance Your Ride: KILMAT 50 mil 25 sqft Car Sound Deadening Mat, an Automotive Audio Noise Insulator and Dampener by Alex Barr

Now I can turn on the music and close the doors. I can't hear any music other than a very muffled bass. At full volume I can't even hear the mids and highs. This only if the inner lining of the door panel is completely lined with this material. I have a BMW 335i so there is built in insulation taped to the metal panels but I could still hear beforehand. Now he is silent. Very strange. This means I can now yell at people on the phone and no one in the parking lot will give me weird looks.
