When a person wants to buy a sound system, he or she needs to buy the correct amplifier accordingly. It is always preferred by a person to buy an amplifier that has the latest features with minimal cost. There are multiple kinds of Amplifiers available in the market today, ranging from different features to various costs in many brands, and two such types are the RMS and PMPO. The difference between RMS and PMPO is that RMS is that when a person uses RMS as his amplifier in his sound system, it is said to give the power value that consists of real-value power output in a speaker, and, on the other hand, when a PMPO is used as an amplifier, it gives the maximum number of output in a speaker.
RMS is the short form for the root square. This is a measurement that is used for measuring the value of output in various kinds of power outputs. This type of measurement is stated to be the most accurate way of how a person can measure an output supple in power output. PMPO is the short form of Peak music power output. This is used by a person for measuring and analyzing the quality of sound that is produced by an amplifier.
PMPO is the highest power at the highest voltage, at the speaker that least less than second. So to be honest, PMPO was created for cheating people at the shops. When we speak about amplifiers, it is power that amplifier can produce at all time, without any damage. There is also some compare with voltages. You can very easily check that by testing current by multimeter and than check at the oscilloscope. You will see that measure instrument will show while amplitude of current at oscilloscope is How we can use that in practice way.
In general, speakers power we split by 2 or3 and we got amplifier, for example: if we hve watts speaker, we can plug it to amplifier with power output abou 50watts. Of course we can plug stronger speakers but not too strong —obviously you want plug a subwoofer to headphones slot. RobertGarcia Newbie level 2. Research shows that RMS watts is defined as the continuous average power when the amplifier is driven with a sine wave while PMPO is the abbreviation for peak music power output which is recognised as the total useless since there is no agreed method of arriving at a figure.

It is used to show how much power a product can output without clipping or failure by plotting different points of a sine wave over a longer period. This is different from PMPO which is sometimes calculated by taking the real power value and multiplying it by a certain number. To get the root mean square, all the plotted values are squared, then the mean of the squared values is calculated after which the square root of the mean is found.
The testing methods can vary from one manufacturer to another. In some cases, a manufacturer can find the PMPO value by taking the supply voltage and multiplying it by peak instantaneous Short-circuit current. Therefore, the continous power rating, in this case, will be 70 Watts. You cannot judge the power and quality of an amplifier or speaker by using the PMPO rating as this is a complete marketing gimmick to make the products more powerful.
