I probably should have posted this in the new guy forum. But I'd rather get made fun of here. So, does an amp supply sole power to a component or does it add to power that a receiver already provides? In other words, if you have a 100wx4 receiver, but you buy a 2 channel amp good for 100w per channel... Does each speaker then get 200w of juice? I'm kind of dumb with this knowledge so please go easy.
