Subwoofer Module amplifier Circuit is indeed very popular with the audio hobbyist. 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 its by the workings of some supporting components such as resistors, capacitors.
The workings of this circuit adds to the gain on the frequency of low tone (LPF), so that the sound output is generated for the subwoofer speaker to be more steady and loud bang, but with the voice that minimal noise, in addition to the performance of the power supply should also be stable, so that it will sound hum was gone. Below circuit diagram , PCB design , and How to assemble audio signal subwoofer module amplifier.

This circuit requires little components, are also easily accessible. for the power supply voltage, symmetric voltage 15VDC required for maximum results. And PCB layout below will help you more easily to assemble.

Next, for the installation, only parallel input audio subwoofer output with tone control circuit , so that if the Volume on the tone control circuit in any state 0, Subwoofer can still set the volume. because the output of the subwoofer module with an output diparalel tone control.
