Uh, wut? There are very few ways the output will remain constant with varying impedance and the fact that 'it's a digital amp' isn't inherently one of them. One way is by using output transformers (like a tube amp or a McIntosh) and I really can't think of any others.

Do you not understand how a digital amp works? The power supply is usually some form of PWM (Pulse Width Modulation) and so to is the output. It varies the power output based on the length of the 'on' times vs. the 'off' times in the modulation.
So running an 8ohm speaker, you can get say 100 watts by the 'on' time being at 100% duty on the modulation. And running a 2ohm speaker, you also get 100 watts because it is running at 25% duty on the modulation.
It is how it limits the power output to operate within safe parameters.
The above is overly simplified but should get the picture.
