    • Use your fingers to pull the top of the speaker grill away from the speaker enclosure.

    • Pull the bottom of the grill away from the speaker enclosure and then completely remove the grill.

    • Four posts attach the grill assembly to the front of speaker enclosure. These posts are located on the back side of the grill assembly.

    • Remove the top two 9.5 mm Phillips #1 screws from the speaker.

    • Remove the two 9.5 mm Phillips #1 screws located below the speaker screws.

    • Slowly work your way around the seam until the two parts of the enclosure are free.

    • More speaker cable slack may be achieved by pulling additional cable through the rear of the case.

    • Inspect both sides of the printed circuit board (PCB) for any raised traces, off-colored areas, or loose components.

    • This step is to avoid making a mechanical repair (re-soldering the wires to the PCB) on a piece of equipment that also has obvious electrical or mechanical issues.

    • Use desoldering braid and a soldering iron to wick away the old solder and wire remnants from the solder pads and through-holes.

    • Do not leave solder bridges across the pads as this will cause functional issues.

    • Use wire strippers to remove a small section of insulation from the wires.

    • Use a soldering iron and solder to tin the wires. This prevents the strands from fraying.

    • Insert the yellow wire into the through-hole marked "R".

    • Insert the bare ground wire into the through-hole marked "G".

    • Insert the white wire into the through-hole marked "L".

  7. ChOxbKU21KZnZgxJ

    • Use the soldering iron to flow solder between each wire and its solder pad.

  8. YN2MrJkSoHOygWVF

    • Reassemble the two parts of the enclosure making sure that the PCB-mounted audio jacks are lined up with the mating holes of the rear enclosure.

    • Route the cable inside the enclosure to avoid stressing the solder joints.

Conclusion

To reassemble your device, follow these instructions in reverse order.
