Would you recommend I use the 1A DC wall power supply instead of the one in the photo above?

For now, only because it sounds like a more simple power supply. 1A should be enough to get you some output. It may not be enough for full volume output.

Is anything getting hot on the board?

And let's double check your speakers also.
...along with the 2 recommended speakers

Can you link to which ones these are.

Sorry for the late reply. Nothing on the board is heating up, should I be expecting any LED signals on the board? Thank you for the advice with the 1A wall power supply, I will use that from now on. I bought 2 of these speakers:

They were recommended by Core Electronics in the MAX9744 details.

Unfortunately, there aren't any indicator LEDs on the board. Let's double check this other power supply. Can you post photos of the 12V / 1A supply you are using now.

Dear Adafruit,

I am working on a very similar project, and am confused about the fact that my power source can only supply 0.03A under 12V DC. I wonder if this is why the audio output has a low volume even though I set the volume to highest in i2c. Could you please provide some input? Thank you!

Best,
Mengjia
