As I've said somewhere else on the site, there's actually no such thing as RMS power. The proper term is average power. I use the term RMS power anywhere that RMS voltage is driven into a resistive load. The purists just hate when someone uses the term RMS power. Since the term RMS power is used by most everyone in the industry, I'll use it here also. It may not be technically correct but it's less confusing for some. http://www.bcae1.com/2ltlpwr.htm
Bottom Line: No one can tell you if you will blow your speakers with a given amplifier. They may be able to tell you whether or not a pair of speakers will be able to handle a given amount of continuous RMS power. But... since they don't know your listening habits or your ability to hear (or even be concerned about) distortion, they (in my opinion) cannot actually tell you if a given amplifier (with you at the volume control) will blow your speakers.
