Step 2: How to Make ?

First remove the enclosure of both Bluetooth Audio Receiver & 2.1 Speaker.

Once you removed the enclosure of Bluetooth Audio Receiver attach the USB Female Cable & 3.5mm Jack to the Bluetooth receiver. Now lets move on to the speaker.

After removing the back cover or the enclosure of the speaker, now separate the amplifier from the speaker casing (Note: Keep tabs of all the wires you remove). Once the Amplifier is separated from the casing, Now Identify the Power supply point and connect the Voltage regulator or the Buck Converter to that point. Now after connecting voltage regulator the important thing is to set the Voltage Regulator output to 5 Volt. You can set o/p to 5 Volt by reconnecting the amplifier to the main supply & then manually adjusting (Suggestion : For better understanding please watch the video which posted along with this tutorial in the first page).

Note : To make your own voltage regulator which was used in this project you can click here - YouTube or instructables

After Voltage regulator is connected, Connect the 3.5mm Jack cables to the Audio Input point in the amplifier.

Note : While Soldering on the board be very careful. I recommend using a pointed soldering rod.

Once everything is connected, Connect all the wires you removed from the amplifier & reconnect the amplifier to the speaker casing & reattach the back cover. Once everything is done, Switch on the speaker & pair you Bluetooth Audio Receiver with you Bluetooth Phone or PC and enjoy your music.
