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). Sooo true A lot of the cheaper manufacturers have ridiculous Max Power ratings. I believe that it goes something like, "If a speaker can handle the power for more that 3 seconds, then it can be rated at that level." So the manufacturer just keep cranking up the input power to a speaker every 3seconds until it pops, then they rate it at the previous level. I'd hazard a guess that amps would be done in a similar level. [Report message to a moderator]
