Mercedes-Benz C-Class W206 Continuous-Rotation Tweeters — Installation Video Guide

This guide follows the W206 rotating-tweeter kit shown in the archived source for CKCP source archive (qCdFYQY). “Continuous rotation” describes the product name used by that source; it does not establish perpetual motion or verify continuous operation. The product image states “2022–2024 C-Class W206” and “64-color inner and outer lighting.” Confirm the actual vehicle, audio configuration, kit and module revision with the supplier; those printed claims are not a fitment or function test.

1. Product and parts reference

The original image numbers the components as follows:

1. 01 — 4D rotating tweeters: the pair of triangular tweeter assemblies.
2. 02 — module set: the image caption calls these “ambient-light modules,” but the physical labels identify a continuous-rotation protocol / rotating-drive module. This difference needs supplier clarification; do not assume the modules' exact functions from the translated caption.
3. 03 — adapter wiring: the harness supplied with the pictured kit.

The printed module identification includes LA_4DRHS01_SV1.3 and a date of 2025/03/31. Match the actual kit labels before using the demonstration as a reference. The translated image also needs correction where an overlay replaces a printed model-code field; it is not a connector specification.

2. Installation video and step navigation

The following navigation follows the approximately 2-minute-22-second source demonstration. It supplements the video with source-supported wording. Connector numbers and wire counts below are descriptions from this particular source, not a pinout or wiring specification. Confirm matching housings, labels and the correct kit documentation before making connections. The video does not establish a complete power-isolation, reassembly, coding or torque procedure.

1. 00:12–00:20 — Door-trim screws. The demonstration uses a T30 driver to remove the two screws shown in the door trim.
2. 00:20–00:43 — Release the door trim. A trim tool releases the illustrated clips. The installer pulls and lifts the trim clear, then releases the two connectors shown on the back of the panel using their clips. Follow the shown positions rather than assuming that another trim or equipment version is identical.
3. 00:45–00:59 — Replace the tweeter assembly. The factory tweeter cover is removed by hand in the demonstration. The replacement rotating-tweeter harness is routed through the existing opening shown in the video.
4. 00:59–01:09 — Seat the replacement. Align the four clip positions identified by the source caption and press the assembly into place. Check the actual clip arrangement on the supplied assembly; the English video's “three or four clips” wording needs correction.
5. 01:09–01:25 — Identify the adapter branch. The installer separates the adapter leads, including the blue/white branches shown. At approximately 01:23, the source identifies the No. 12 connector and demonstrates the blue adapter branch. “No. 12” is the source designation; the English video's “12-pin connector” is not supported by that designation.
6. 01:27–01:42 — Lighting and module branches. The source next describes a four-wire connector for the lighting branch, followed by a connector labelled 5P and the red plug shown. The English video's “4-pin plug” wording must not substitute for the source's wire-count description. Use the demonstration only to locate these shown branches; their cavity assignments, electrical ratings and interchangeability are not supplied here.
7. 01:44–02:12 — Speaker adapter branches. With two speaker-lead sets remaining, the installer disconnects the white midrange-speaker connector, fits the illustrated module adapter, connects the rotating-tweeter speaker lead, and returns the adapter connection to the midrange speaker. The exact mating arrangement must match the depicted kit. The source supplies no electrical pin assignment or universal audio-system compatibility claim.
8. About 02:16 — Installed appearance. The sampled closing view shows the installed illuminated tweeter assembly. It is a visual result reference, not evidence that rotation, sound quality, lighting modes or completed vehicle reassembly have passed testing.

Some current English subtitles contain connector terminology errors and incomplete sentences across cuts. Confirm the source labels and this guide's distinctions until the local English subtitles and narration have been corrected and checked through the full video.

3. Installation result

The original article's separate result section contains no additional effect material. The linked installation video provides an installed appearance near its end. A complete source-specific demonstration of rotation, audio output, lighting control and final reassembly is still needed before reporting functional acceptance.

4. Troubleshooting and missing technical information

The original fault section contains no diagnostic instructions. No reset, coding change, pin swap, voltage, torque or wiring remedy is established by this source. If a function is abnormal, give the supplier the vehicle and audio configuration, exact kit/module labels, observed symptom and clear photographs of the relevant labelled connectors so that the matching instructions can be identified.
