So... you want to know how much the SA-12 will take thermally ? Video starts at 14.5 amps (1740 watts) power drops off to the 1200 - 1400 watt range after the first 10 seconds and continues to play for a total of about 35 seconds at this power level.
Never going below DOUBLE rated power for the entire time on straight sine wave wall socket power @ 60 Hz. The woofer is NOT broken but I decided to stop as the current continued to drop indicating the coil was getting too hot. I plan to use this one in my Jeep so I didn't want it to go until it quit //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

This is a Dual-2 -- first sample that I built yesterday -- so nominal load was 4 ohms. I didn't use the Dual-4 (production) since it would be either 8 ohms (not much power) or 2 ohms (too much power).
