10 Watts RMS at 4 ohm, for example, mean than an amplifier can output a clean 10 watts of sound into a 4 ohm speaker, in the full audio range, thus being it's realistic power.
R.M.S. stands for "root mean squared", which is your mathematical way of finding the average (ergo "mean") output power of an alternate electric signal.
Kind Regards,

| difference between Peak and RMS |
|
|
Also note that there is a big difference between Peak and RMS.
Peak, as the name says, will indicate, the max power it can have. So 10 Watt Peak at 4 ohm mean that an amplifier max output will be 10 watts of (probably distorted) sound into a 4 ohm speaker, at the perfect frequence(s).
So it is important to always check the RMS value of a speaker or an amp before buying. If only the peak value is indicated, RMS value is always at 70% of the peak.
