low pass filter for subwoofer amplifier

low pass filter for subwoofer amplifier:

 This is the low-pass filter for the subwoofer amplifier. This circuit needs to make a bass amplifier. We also need to make a 2.1,5.1 audio sound system. This board makes only bass. makes only the low part. It has no mid-range or high part. It’s also a pre-amplifier. It’s output mono. Input stereo but output mono. This board runs on 9 volts to 15 volts. It needs a single voltage. For this, we can use this board in the car amplifier. 

This board is designed with 4558D. We can also use the NE5532 IC. It has 2 volumes to control the sound. One is the master volume, the one is the frequency volume. The voltage requirement is 12 volts and 2 amperes.

Bass tone circuit for an amplifier

This is the bass tone circuit board for the amplifier. This circuit has four volumes: volume, low, mid, and high. This diagram runs on 12 volts. It’s a mono diagram. For stereo, we have to use the dual board. It needs a single positive and negative voltage.
