Lets start by going over speakers and amplifier ratings and what they mean.
The difference between “Peak Power” and “RMS Power” is simple, so don’t let it confuse you. RMS Power is a measure of the amplifier’s continuous power. It’s the realistic amount of power that the amplifier is rated for. It’s more of an average of the wattage output over a set amount of time. Peak Power can best be described as the “peak” amount of power that the amplifier can generate or handle in a very short amount of time, a burst. It is not the amount of power the amplifier emits on a continuous basis, but more of a quick burst.
Even though the Peak Power ratings are marketed by speaker and amplifier manufacturers to catch the eyes of consumers, it is not the Peak Power, but the RMS Power that you want to use as a tool to match the right speaker with the right amplifier.
