Meaning of RMS is root mean square also known as the quadratic

mean, is a statistical measure of the magnitude of a varying

quantity. It is especially useful when variates are positive and

negative. It can be calculated for a series of discrete values or

for a continuously varying function

### What is rms to watts in speakers?

If suppose you have 350 watt speaker with 100 watt RMS, then
that 350 watt is a peak rated speaker, with a true 100W RMS rating.
The 100W RMS rating is thermal, meaning it can withstand the heat
of 100 watts of power. Anything above that is risking it, but
remember that a 100W RMS amplifiers is only going to produce it for
a little while due to the dynamic nature of music. You'll rarely
use all that power. That being said, if you're careful not to
overdrive the speakers, a 160W RMS amplifier won't hurt a bit.

### How do you calculate RMS power?

Power is determined from an AC voltage measured in volts RMS and
an AC amperage measured in amps RMS, but there is really no such
thing as "RMS power". People are using the term "RMS power", but
that is not correct. it is actually "average power".
Why there is no such thing as 'RMS watts' or 'watts RMS' and
never has been:

### What does watts RMS mean?

Watts root mean square is the effective value of
alternating current electrical power compared to direct current
power. In AC there is a rms or effective value of voltage and a rms
or effectice value of amperage. Power is volts rms times amps rms.
That is the AC watts compared to direct current power. There cannot
be RMS power or watts RMS. Scroll down to related links and look
for "Why there is no such thing as 'RMS watts' or 'watts RMS' and
never has been". RMS watts is meaningless, but we use that term as
"an extreme shorthand" for power in watts calculated from measuring
the RMS voltage.
