I've personally tried out both products and I have to say that the Rockville sound suppressing mat is just as good if not better than the Dynamat. It's thinner too so it doesn't push out you car's interior pieces when you put it back together. With the Dynamat I had to keep taking pieces off so that my door panels and other interior panels would go back on. Leaving you with less coverage. I'm running a huge amount of power in my vehicle and I don't want it to sound like a soda can with rocks in it when it hits and I'm at a red light. It sounds almost as good on the outside as it does inside. Doesn't sound cheaply done anymore. I don't know how the rest of Rockville's equipment is, but they did a great job on this. Plus it's half the cost of Dynamat.
