i need someone's help to know how the heck to cut off power to my sub (after the amp) if its below an ajustable point, i hate my crossover, and its for a school project so thanks to anyones help 8)

So what you are wanting is that at a certain volume level the sub turns off?

yeah, either before or after the amp actualy it doesnt really matter, i hope. so long as it cuts out any signal to the sub that's below about 10% of its maximum output. its a 1500 watt system running at 2 ohms so 10% should be somewhere around 5 volts, although that doesnt sound right.... meh. but i figured it would be a little more then 27 amps. :idea:
