Step 1: Open the Enclosure

use your Screwdriver loose all the screw you see.

Step 2: Identify the Audio Output of the Bluetooth Module

All Bluetooth Speaker or earpiece has A Bluetooth Module and Amplifier Module.

SOMETIMES IT'S A STEREO TYPE BLUETOOTH MODULE LIKE Blk-MD-SPK-D BUT IT'S JUST THE SAME PROCEDURE.

you must find it's datasheet to identify Where are the trace of Audio out of the Bluetooth Module and the Audio in of the Amplifier.

Example in my case i Have a AC1526E64753 Bluetooth Module Which i couldnt Find it.

So Second option Find the Audio input of the Amplifier in my case Ltk8002 a Class ab Amplifier that has audio input in pin 4 so you need to trace it back to the BLUETOOTH MODULE to get the RAW SOUND W/O Filtered by the resistor and capacitor in Amplifier USING YOUR MULTIMETER.

Step 3: Soldering and Hot Glueing Your Wire and Audio Jack

This is when you successfully find it's trace back to IC and solder the pos+ wire and Neg- to the AUDIO OUT of Bluetooth Module.

Secure it with some Hot Glue and Heat shrink tubing.

Step 4: TEST IT!

BEFORE CLOSING IT UP CHECK IF IT WORKS PROPERLY.

Step 5: Closing It Up!!

Drill a Hole to it's enclosure use your screw or anything sharp obj to make a hole put the extended wire to and close it up.
