Root Mean Squared (RMS): A term used to indicate the average level of power that a receiver or amplifier can sustain over a given period of time. Average power ratings (ex: 100 watts RMS) provide a more realistic assessment of your amp's performance than peak power (ex: 400 watts peak/dynamic power) since an amp can only sustain peak power for a short period of time. (RMS stands for 'root mean square,' which is one of the mathematical methods used to calculate an amp's average power output. While it isn't an accurate descriptor of the measurements themselves, it's commonly used throughout the industry to denote the average power rating.)
