Exactly why I was so mad I stopped with the Dynamic tests. My set up isn't the same as as n AD-1, so I have to do all the certified test is succession (Going from 4 ohm working down to 1 ohm), then I have to reset the amp for dynamic testing as you have to adjust the gain which involves hooking up the DD-1, then I have to mess with the resistors to get the load.
I had a lot of hope after doing the main channels, even weighing down the amp with a static load on all channels the 4 channel section was able to achieve 67x4 (71x4 at clipping), and was even underrated bridged. Then I tested the Sub channel.... As soon as I saw the 156 at 4ohms I was instantly disgusted.
