To much power to sub

Im willin to bet 25 of your 45 post are on clippin:p:
i will be totally honest: it's the one "Car Audio Wives Tale" that i detest the most, as it is passed on so often with little information than other "oh, that's clipping." no discussion of the actual electrical basis of clipping.

 
a sub is typically less than 1% efficient anyways, so this "added cooling" from excursion during a sine wave is moot. almost all power is lost thermally anyways, so that's a very inaccurate argument, although the one most commonly used. there are also several tests that have corroborated this information, showing that speakers routinely died at the same power level, whether they were clipped or un-clipped.
There was a test done on one of these forums and it proved it first hand:)

Although I cannot cite my sources simply because I cannot remember:crap:

 
No a fully clipped signal is not DC it is an approximation of a sqaure wave with the crest of the square made from the summation of pretty much every harmonic of the basic signal.

As far as the cause goes, the output stage of the amp is trying to produce a signal of higher voltage than the rail voltage produced by the amp's power supply. The standard cause is overdriving the input of power stage either through to high a signal voltage from the source or overboosting the signal in the amps dedicated preamp stage.
