Rms Amplifier
Posted on Tuesday, September 28, 2010 in Car Amplifiers
What is the Rms wattage of a 2 channel 200w amplifier?
hi i am buying a 2 channel amplifier from ebay and it says on it that the max output per channel is 100w, but i need to know would the RMS be 50w per channel?
It depends on whether the amplifier's max power output per channel is rated as "Peak", "Average", or "RMS" power. It could also be a Peak Music Power Output (PMPO) rating.
If the amp's advertised 100W rating is a "Peak" power rating, the answer to your question is "Yes."
(RMS power would be approximately 70W per channel.)
If the amp's advertised 100W rating is an "Average" power rating, the answer to your question is "Yes." (RMS power would be about 60W per channel.)
If the amp's advertised 100W rating is an "RMS" power rating, the answer to your question is "Yes."
If the advertised 100W rating is PMPO, then the answer to your question is "NO." In this case, the RMS output power could be as little as 10 watts.
I suggest that you obtain the amplifier's Make and Model Number, and then do a little on-line research to determine the correct power rating for the amp from the manufacturer or reputable source (like CNET or an industry standards organization).
