Finding the ideal model for your application may often be tough. There is a large number of different names and technical jargon describing mini audio amplifiers, like “Class D” or “T-amp”. I will present a quick overview of the output wattage specification with the intention to help you better understand the meaning of this specification and how it relates to the functioning of an power amplifier. Let me now go ahead and clarify the power spec of stereo amplifiers.
“Wattage” is from time to time also known as “Power” or “amplifier output power”. You wish to select the amp wattage depending on how large your listening environment is. However, “rms power” describes how much power the amp can output for a longer amount of time without being damaged. Nonetheless, whereas the rms rating is going to tell you more about the amplifiers real performance, be sure however that the amplifier offers a peak power rating which is quite a bit bigger than the rms rating. the power envelope of the audio is going to fluctuate over time. Short peaks of high power are repeatedly found in audio signals. These bursts are going to drive the amplifier into large distortion unless the peak power is large enough. Typically the impedance of the speakers that you connect to the amplifier will determine how much power the amp may deliver. Hence the largest output power will differ depending on the loudspeaker impedance.How Much Wattage Will You Need From Your Power Audio Amplifiers? by Pat Mitchell
