circuit diagram

In this post I make a low pass filter for subwoofer. Now watch the circuit diagram and follow my steps  for make this circuit. first you need a 4558 ic . short ic's 1 and 2 no pin, then connect here a 104j capacitor and a 1uf  capacitor (+). Then connect a 100k resistor with the 104j capacitor and ic's 7 no pin. Then connect a 22k resistor with ic's 3 no pin and the 104j capacitor. Then connect a 104j capacitor with ic's 3 no pin and ic's 5 no pin for ground. Then connect a 100k resistor with ic's 6 and 7 no pin. Then connect a 1uf capacitor (+) with ic's 6 no pin. Then connect 560 ohm resistor with ic's 4 and 8 no pin.

Ic's 8 no pin resistor (560 ohm) is +12 volt, Ic's 4 no pin resistor (560 ohm) is -12 volt. Ic's 1 no pin capacitor (1uf) is output and Ic's 6 no pin capacitor (1uf) is input.
