[QUOTE="microhaxo, post: 5452606, member: 570733"] So which method of calculating RMS is accurate to run the subs at? w = v^2 / ohm (which this cant be if you assume that the factory rms rating is actually a root mean square) or w = a * v * efficiency of amp (more could go here) ( this seems untrue as well because in an attempt to attain an actual RMS power to the subs i found that they couldnt handle them) So since i am running my Sub at 40v off of the amp at a 1 ohm load that must mean that i am running at 1600w rms according to 85% of the car audio enthusiasts on this forum. (which is unlikely since the PEAK rating on my sub is 1200w. Not to mention box rise but we wont get into that..) [/QUOTE]
