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 :)

Fun stuff :)

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).

Part II at 2 ohms this time !

Way too much power but we did it anyway! Played 19 seconds before failure at 400-600% over rated power. Started at 3720 watts and dropped to 2472 right before failure (multiply the current by 120 volts). Don't try this at home.

Just to be clear this is the standard coil not the SPL Coil???

If you build it, db's will come...

NSPL World Record Holder Trunk 0-1800 watts---147.9 with 1722 clamped watts @ 40Hz(9-20-09).

Competition Only Record Holder Trunk 0-500 watts---148.1
