My SUV's door panels are vibrating with heavy bass songs and there are two places that will put either Cascade or Dynamat sheets on the doors and floor. Is there a big difference between the two brands? I ask because the Dynamat would cost me about $400 more than the Cascade to install.

Thanks in advance
