4 ohms and 8 ohms


I am always wondering how this works:
Speakers came with different ohms and so does amps, how does amp knew which ohms to use when there's no switch on the amp?
Example: speakers rated at 4 ohms and the amp rated at 4 ohms and 8 ohms without switch of ohms, how does amp knows which WPC (8 ohms 100wpc and 4 ohms 200wpc) to use?
What happend when speakers rated at 2, 5, 6 ohms?
Thanks a lot for your explanation. ^_^ ^_^ ^_^

I don't know in detail the technical side of your question, but the amps receive a load from the speakers and they adjust the power they put out accordingly
