How to make Simple Bluetooth Speaker

In this video I had made a super simple and also cheap Bluetooth Speaker.
This is awesome because its super cheap and the battery backup is also awesome (up-to 7 hours) without charging. I had used 21 gauge pure copper wire that make crystal clear sound and also bass is good.
The Speaker test may be not good because of my camera microphone not good but amplifier sound is so good.
Parts Requirement:-
1x Bluetooth Module
1x 5V PAM8403 Amplifier
1x TP4036 1A Li-Ion Charging Module
2x 18650 3.7V Li-Ion Battery
1x On/Off Switch
