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. And that means you hear more music.

Dynamat Door Kits come in two levels of performance. The Original Door Kit offers the best value for the money. The Xtreme Door Kit controls vibration four times better than Dynamat Original and requires no heat for installation, which makes the Dynamat Xtreme Door Kits a great choice for do-it-yourselfers.
