After removing the screws you can upen up the case. The circuit board is fastened with another four screws that have to be removed. Then the board can be pulled out of the case carefully. The power button of the speaker is the most sensitive part here. To make life easier, you can also pull off the speaker cables from the board. Now the cover is completely separated from the bottom and the circuit board.

The next step is to drill the three mounting holes into the cover, for which you can use <a href="misc/JBL_screws_drilling_template.pdf">this template</a>. Finally, we need to mount the base of the printed case to the speaker case using thee M3 screws with nuts. Afterwards, we can put the circuit board back in the case and put all the screws back in place.

The three buttons go directly in the small pockets on the bottom part of the printed case. While the front pins are put into the small holes in order to fasten them tightly, the pins on the other end should be bent up. I ended up soldering some F-M wires directly onto the pins, but using F-F wires is also an option. Connect the buttons to pins 9 (for PREV), 10 (for PLAY/PAUSE) and 11 (for NEXT). The other sides go to the ground pins 20, 30 and 34.

While the front pins are put into the small holes in order to fasten them tightly, the pins on the other end should be bent up and soldered to the male end of the jumper wires.
