Bellow is a Bluetooth speaker boombox diagram. I am just new in electronics and the diagram was just a layman sketch. I want to know if such wiring is correct, due that is not all the components of the project but this is the one I really want to if I got it right.
In between the led switch and the amp, is a boost converter that guarantees a 24v power to the amp, but I omitted it in the diagram. Pls I need an opinion if I get this right here.View attachment 182116

First, could you rotate the pic 90° to the right and update your post? Difficult to read it sideways.

Secondly and most important, this is a wiring diagram and not a schematic. What appears to be your switch is hard to understand. What are the specific contacts you are connecting to? It looks as if the switch creates a direct short across your battery. Can you provide more detail of the switch.

And thirdly there appears to be a little magic happening. You have 16VDC into a jack and 12VDC out. What?

that seems to be a connection for external power supply, not 12v output.

Yes, it does!

OK, I will update it, and this time more precise.

 

The TPA3116D2 datasheet (from Texas Instruments, not a Chinese knock-off) shows an output of 30W at low distortion into each 8 ohm speaker when the supply is 24V , but 40W if it is turned up producing severe distortion. That will kill your battery and speakers.
If the speakers are 4 ohms then the IC will also be destroyed.
