Subwoofer Module Amplifier using 4558 with PCB

Subwoofer Module amplifier Circuit is indeed very popular with the audio hobbyist. The circuit that I publish, is a circuit of modules that use the subwoofer amplifier ic op-amp 4558 which acts as a reinforcement of bass tones (subwoofer) assisted of it's by the workings of some supporting components such as resistors, capacitors. 





The workings of this circuit adds to the gain on the
