Johnny...
i totally agree with what you are saying from a strictly engineering point of view.... however, we are talking about the wolrd of car audio here, something which rarely follows the rules and convensions of physics and electrical engineering principles.
Mainly this has to do with the PMPO ratings that car audio brands slap on their products. There is no definition in the car audio world of what PMPO should be, hence manufacturers make their amplifiers produce ridiculous amounts of PMPO at millisecond intervals and claim that to be the rated PMPO for that amp (at least the dodgy ones do anyway). In which case, the rule that RMS = PMPO divided by sq.root(2) does not apply, since they arent even using sine waves anyway.... believe me, i've asked some manufacturers (eg. pioneer).
And what toobs has said is correct.
