Honestly, I think because of the increased output the 20.1 did make the Mags sound better than the md2. Even though they are both rated around the same at 2 ohms, it was pretty clear that the 20.1 was putting out more power than the md2. I have been playing different frequency tones for weeks and listening to them with the md2, and after switching to the 20.1 and playing those same tones I noticed some very noticeable changes. It just seemed like the subs were getting more power, and the sound was more clear. It just has a more crisp sound to it.so the 20.1 made the sub sound much better and was 10x better than it at 2 ohms ay
