POSSIBLY not acheiving full performance.

It is 100% possible to power a sub to full potential with much less than RMS power......as it depends on the enclosure. Not to mention, there is not standard for rating RMS. Some rate it as simply thermal power handling. Some rate it as an "average" power level in most boxes. Etc etc. Which also makes it very hard to determine how much power is needed in a given application to achieve full performance.

^^ lol

oh yeah i forgot box design could make up for power to a certain extent

Ok Ok so if my rms is 1000 and run a 650, and building a ported box so I make it smaller or larger or what.

rms is the root mean square value of the wattage you will send to the sub.. in other words the industry tries to give an "average" power it will take.. the power will peak at certain points in a song.. if you go below the rms value.. nothing bad will happen besides not reaching its full potential.. if your sub is 1000 watts rms.. at 800 watts, potential doesn't mean that much.. thats still pretty **** loud...
