with a input of 500mV, If you change the gain to 2V and show it a signal of 2V, it's still 200watts. If you show it 5 volts now, it most likely will produce more power, but the onset of distortion comes rapidly as 2V is surpassed, and it will begin to sound like crap quickly as internal components reach their max operating ranges with damage resulting eventually to the amp, and or speakers etc.
This is a good example but it is backwards, the lower the number on the gain (500mV) the higher the output will be but you will be well on your way to achieving a clipped signal.
