Dynamat Lowers Road Noise!
Don't Buy Half A Sound System Why does your car stereo sound louder when you pull off the freeway and come to a stop? Road noise steals much of the listenable portion of your music. At 70 mph, a typical automotive noise level of 85 dB leaves you with only 20 dB of listenable music. Applying Dynamat creates a "sonic barrier" restoring 3, 6, even 12 dB of lost dynamic range. Gaining just 3 dB doubles your effective amplifier power. (Doubling your sound) And that means you hear more music.
