Hey, Sorry for replying late. Been out of teambhp for a while. You can find amplifier boards on Amazon or on SP road as well. The one you see in the picture is a TDA7492p 50w RMS board with enough power to drive these and larger speakers. I power it with a 12v 2A supply or an old laptop power brick as these run on a wide voltage range from 12v to 24v.
I had bought many such boards from Aliexpress for cheap back when it was available.

A good amplifier, clear sound, the only drawback being absence of auxiliary input port, and maybe shorter bluetooth range. All these boards need a ac to DC converter.

This is also a good amplifier. I had bought this from banggood for about 1200 few years ago. But the TPA series boards like this one aren't as clean sounding as the TDA chip based boards. Also they get bit hotter. The bass channel is pretty weak on mine and the bluetooth range is also limited. But the left and right channels are very punchy.

There are newer boards like ZK-MT21 and the one that I've eyed for a while, the ZK-HT21 or clones like XY-S220H

They are really good for music. If you've speaker boxes that has three channels inbuilt (mid range speaker, tweeter and maybe woofer), these boards can be used for movies as they are mostly geared towards low end and may have some bass in the dialogues.

If you've a crossover circuit, utilize that to split the audio to two or three ranges to utilize these boards to their fullest.
