The circuit use TDA7388 as the power amplifier and it upgradeable to TDA7560.
For the Active Lowpass filter, I use NE5532 IC.
I design this project suitable for car subwoofer, motorbikes audio modification event, home, and everything that come with 12V battery or transformer.
The circuit is made as simple as possible with standart through hole Components that easy found on the store.
There are 2 potentiometer settings :
-Frequency cross over
-Subwoofer Volume
It need single supply 12Volt/10-15A
If use with transformer, you may need external bridge diode to make DC voltage.
