[QUOTE="Shonver, post: 930395, member: 34"] Just to clarify: the amount of power that the amplifier pushes into the speaker is not determined by the amplifier's rating; it is determined by how loud you play. In other words: the volume knob. Motor car analogy: the top speed of a car is usually determined by the power that the engine is able to develop. Thus, a car with a more powerful engine will have a higher top speed than the car with a lower power engine (all other things being equal). What happens when you try to take a car over its maximum speed? It simply tops out and doesn't go any faster. No harm done. What happens when you try to take an amplifier over its capable power? Lots of clipping: an unpleasant experience! So, what is the difference between using a lower power amp vs an amplifier of higher power capability? If the output of the smaller amp is high enough to play to your required maximum volume level without clipping, all is good. Then, when you substitute with a larger amp, what then? If you listen at the same volume level: nothing! The new amp will still push the same amount of power into the speaker to achieve the same apparent sound level. Even if has another 100W in reserve! You don't need to change your amp. [/QUOTE]
