I was thinking to reuse an old pair of speakers. I come up with an idea of making a mini bluetooth amplifier.
I found this extremely cheap PCB (YXY-CY05) at around US$4. The board has bluetooth and aux input with 5W power output. We can use any 5V adapter to power it up.
The size of amp enclosure is about 8x8x4 cm, just big enough to put all the components in(PCB, power button, DC and the speaker jack).
To my surprise, the amplifier produces punchy bass and performs well at vocals too.
