Q&A 1. How to choose a power supply? The power adapter for the amplifier board is important. Higher voltage and higher current will bring be�er output power. If you use a 12V 1A power adapter, the amplifier board can only drive 3-4in speakers. If you use a 19V 5A or higher voltage power adapter, then it can drive 8-10in speakers.
