I want to make sure I have this right because I am reading and hearing different and misleading opinions regarding power ratings.
There are the terms "RMS", "Program", "Continuous" and "Peak" describing speaker power output I have seen. However, when it comes to the first 3 terms, it appears they always get confused.
Correct me if I'm wrong, but RMS (root mean square) just means average power. The Program rating is the one you should be focused on.
I am seeing different descriptions about "continuous" power however. Some places use that synonymously with RMS, but I think that's wrong. It should be the same as Program power, correct?
Anyway, I have an RMX2450 QSC amp with specs at 500W per channel at 8 ohms. I assume this rating means the Program or Continuous power, not RMS. I have Yamaha S115V speakers with 250W RMS/500W Program/1000W Peak.
I have read that these are a good match. Others have told me your amp power should be higher than the speaker power generally. I don't know if that means the Program rating of the amp (which is usually twice the RMS rating) should be higher than the RMS or Program rating of the speakers.
I appreciate any further guidance on this subject.

i can tell you as far as
RMS is the speakers output rating which it can output continually for as long as required with top efficiency and without problems.
PEAK is used to give the speakers a boost of power when needed for louder signals in short periods (not exceeding the peak rating). it is also the maximum the speaker can be pushed without it being damaged.

After looking into this further, it seems that RMS is the same as Continuous and when matching up, the amp's power rating at 8 ohms should be somewhere between the speaker's RMS rating and the Program rating.

that amp is fine for those speakers.
