Bluetooth Siare Speaker with LM386 playing old Dutch air raid alarm

When I was young I had a Radioshack 150 in 1 kit, which, if you replaced one of the capacitors, was almost able to replicate the air raid alarm in the Netherlands. I hooked it up to a Siare 12 Ohm speaker I had at the time (unsure which device I took it from). It was very loud, and I enjoyed playing it out of the window when the actual air raid sound was going off (around 1981).

I still have the speaker, so I decided to put it in a box, add a DC-DC converter to get 12V for the LM386, a bluetooth module, a LiPo battery and charger, and, obviously, have it play the air raid sound once again.

The sound played comes from playing https://www.youtube.com/watch?v=ENHpFkKiyrU on my desktop computer.
