Re: audio amp

Sure you can .. but if you would like to have full 2W outut power you should have an amplifier of roughly 50% more power than speaker rating (difference between sine wave and real sound) ..

As for matching power ratings between speakers and amplifiers, it is not necessary. Most speakers can accept clean input power in huge amounts before destroying themselves. Any quality amp that can produce enough power for your loudness expectations should work fine. The only advantage a 200 watt amp holds over a 100 watt (of the same design) is the ability to play 3 dB louder.
