Class-D amps draw less current than Class A/B amps...
Also, a lot of Monoblock sub amps have a built-in bass boost to them, even if/when the adjustable boost is set to 0, the audio path is boosted, that may partially explain why it hits harder now. Additionally, the caps inside those old school amps need to be replaced as they lose capacitance over time, which would also partially explain why the new amp would hit harder.
Either way - I have always liked the look of those Polk amps, glad to hear that it was a good upgrade for you!
