DIY Simple Bluetooth Speaker 2x3w amplifier + 2x15w speakers (BASS BOOST)

Hello everyone. Here is the another Bluetooth speaker in unusual design. Very powerful and loud sound. Sorry for my bad mic. I used amplifier 2x3w and speakers 2x15w full range and I don't understand how it's working like this, but how we can see it's working very well. Hope you enjoy this video, don't forget to subscribe to my channel. thank you all and have a nice day. See you next time.

NOTE: I have connected 4.2v battery but this amplifier working at 5v, so you can put inside dc step up converter and boost it 5v for more performance.
