It was already said above, but in different wording:
The volume knob decides how much noise (Watt) the amp puts out. With the exception of extreme cases, you can easily connect a 2,000 W amp to a VS112, at the cost of having to be careful with the volume knob.
Also, because of the inner workings of speaker elements, it is not so that 2,000 W will move the speaker cone 10 times as much as 200 W - far from it. There's physical laws there that I don't remember, but maybe someone can chime in there. I seem to remember that logarithmic scales are oncorporated here - not sure though.
It's a different theme altogether really, but in similar fashion 2,000 W will give noise that sounds only twice as loud to the human ear as the noise put out by 200 W.
So, using a 2,000 W amp mostly means you have to be careful with turning the volume knob. In some cases it would mean you can hardly move it.
