[QUOTE="hispls, post: 8451562, member: 614752"] I know for a fact your subs weren't getting full power for long because you didn't burn up the coils. You really don't understand how AC works do you? 1200W square wave = 1800W sine wave period end of story. If you're implying that the cone isn't making the same number of strokes per second (to cool itself) with a square wave vs. a perfectly rounded sine wave you definitely need to visit an autism specialist. Draw a graph with a zero line, a +1200 line and a +1800 line and a -1200 and -1800 line. Now draw a sine wave 1800 + and - peaks and shade in the area between 0 line and the waveform. That is your RMS average power. You can do the math (peak X .707), use graphing software, or just count the shaded squares of your graph paper to verify. Now draw a perfect square wave (likely never going to happen real-world) with 1200 + and 1200- peaks and shade in the area. You will find that it is the same (I'm using 1200 and 1800 for simple rounding but it should be close enough to illustrate th e point). [/QUOTE]
