[QUOTE="gunz4me2, post: 6452190, member: 613729"] Funny thing about statistics and how one can skew the results to make them say anything they want, isn't it? With ohms law, one technically needs two the values to solve for the final (i.e. Watts = Voltage^2/ohms). Voltage at measured impedance would suffice and/or the use of an ammeter. Then again, technically you are correct because the higher voltage would generally be at a higher impedance, BUT that impedance is TOUGH to measure while a subwoofer is bouncing back and forth. I wish you luck in getting that exact voltage at a particular impedance level for a millisecond to perform your calculations outside of a scientific lab. Sadly, even with an amp clamp it is quite possible to see the appropriate amperage pass through when multiplied with the voltage to simulate a higher power output level than is technically possible. I've performed the power measurement tests myself both ways utilizing an oscilloscope to determine clipping in addition to borrowed, properly calibrated Fluke instruments to determine voltage and amperage. In 80% of the cases, I've observed higher output levels just prior to clipping with subwoofers, i.e. your precious "real world" reactive load, than into Dale dummy resistive loads. The bottom line is no matter how you slice it or dice it, a reactive load is [B][COLOR=Red]NOT[/COLOR][/B] a true representation of how an amplifier will perform to provide "real world usable power". We are going to be in permanent disagreement on that one. Pot -> Kettle -> Black...[IMG]//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif[/IMG] [/QUOTE]
