[QUOTE="ShadowElky, post: 8377866, member: 664656"] I was attempting to clamp test my amp earlier, its a Pioneer GM-D8601. The SA-15 its powering is wired to 1 ohm and being that the amp is rated 800w@1ohm and everyone says it will do rated, I am confused. I put on a 40hz test tone turned the volume up til I could hear the sub tone change, then backed it down 1 notch. At that point the voltage coming out the amp was 32.7 and the amperage (assuming I had the clamp set properly) read 8.4. Doing the math makes that only 275 watts. Yet if I use the other calculation for wattage (voltage x voltage ÷ impedance) it comes out to 1070. Which math is right? BTW, the clamp I was using is a Klein CL2300. [/QUOTE]
