first thing, not ever manufacture rates there products the same. I think it is more important that you do not clip you amp and preventing this your speakers would less likly have a problem, remeber a system at full volume is not producing the same continous wattage because the music it self changes and different fq and intensity of the sound increase/decreases actual output, i would rather over power a speaker than under power it, that is the real use of the gain and preventing clipping (which id dc voltage to your speakers) will save you equiptment
