TPA3118 is a very common chip used in many kinds of audio equipments. You you build guitar or bass amp (with suitable pre amp), active subwoofer and much more with this small and low cost board.

Please note: Class-D amp modules can easily be destroyed if the supply voltage is too high, supply voltage polarity is not correct, or speaker impedance is not right.

Please note 2: There are lots of different low-cost Class D boards available. Some are great, some decent, and many are not that good. Some do not even work at all. We have tried many different boards and preselected ones that have a good price to quality ratio. We have measured and listened to every design in our audio lab. We try to be as honest as possible and tell the truth about quality. We also publish modifications if we found a way to improve sound quality.
