Do I see the music player is on in the pic there??
Yeah, lol
There is no battery in the parts car but I've got a 12V transformer powering the stereo and 20 feet of speaker wire running to a speaker in my backyard.
I sit in a chair out back and listen to the radio and feed peanuts to the squirrels and blue jays.
I siliconed a speaker into a coffee cup to make an encloser so that I get more bass. Lol
It kind of makes sense that you have a custom stereo and painted your instrument surround.
You may need to add some more Mg to their diet. I see early deficiency signs on the leaves.
