Salam sir, guys like these are best left at their own, they are too smart for their own good and will come to senses one day.
Regarding the sub blowing an amp, yes sir it is possible, but that doesnt demonstrate the brute force of a sub
Instead what it shows is the uber smartness of the user. How? Put such an impedence load on an amp that it is not stable at and it will blow out. Actually blowing out an amp isnt hard. 
Get a cheap Chinese amp
connect subs at 0.5 ohm. Full bass boost, full gain .. magic formula ready
now it is a waiting game to see whether the sub blows first or the amp. The sub here since is a branded old school sub, it won and the amps lost their poor cheap lives:

and regarding the rms vs peak power ratings, ask the guy to check this out

RMS power vs. peak power
[I]Don't be confused by "peak power" and "RMS power" ratings. Simply put, RMS wattage ratings are a measure of continuous power — while different manufacturers will use somewhat different methods to come up with these figures, it's usually a more "real-life" rating of your equipment's capabilities. Peak power, on the other hand, doesn't try to reflect realistic operation. It's simply a measure of how much power can be generated or handled for very short bursts.
Many manufacturers emphasize peak power ratings by stamping these ratings on their subwoofers and amplifiers. As we noted before, peak power ratings are not realistic measures of the true power capabilities of the equipment. By comparing the RMS power rating of the sub and the RMS power rating of the amp, you'll have the tools you need to pick the right equipment. [/I]
Rest let him just be, some people cant just be educated, for them there is the facepalm
