Small but powerful Class D amplifier with Bluetooth 5.0 multipoint pairing

I bought 2 pieces of Wuzhi ZK-502H Class D amplifier with built-in Bluetooth 5.0 to test if I can transmit two audio signals on two amplifiers, and I was able to stream audio to two amps.
I bought them online for around USD10 each. They have TPA3126D popular Class D Amp IC that can drive up 50W x 2 channels @4ohms speakers powered by 24V/3A laptop adaptor

merun ako nian sir, , speaker ng lumang aiwa components gamit ko, sounds ko sa tricycle, kaso naka 12volts lang ako kaya di gaano kalakasan, pero quality naman ang tunog, , lalo na kung flac files.

I made this. It works great but I added a fan to keep it cool.

I want to use on of these to power a small subwoofer. Does it turn
off/on by pressing down on the volume knob so that the the volume stays
at the same level each time that it is turned on, and will it
automatically use the aux input if something is plugged into it or does
that require anything special. just trying to figure out if I can
simply turn it off/on as needed to power the subwoofer without having to
do other things.
