I tell you bro, I had my US Amps MD3d in my car with the gain set at 1/2 and bass boost at 1/2. I hooked this up with with the settings at gain 1/4 and zeo bass boost and I was like WTF? This amp was way louder and made me notice a hundred more things rattling in my car compared to the US Amps. I have 2 layers of Dynamat Xtreme too.
