Installation Guide
The Audio System MFIT W205 EVO is designed for a custom fit in Mercedes C-Class W205 and S205 models. While designed for compatibility, some adjustments or careful handling may be required during installation. Professional installation is recommended.
General Installation Steps:
- Preparation: Ensure the vehicle is turned off and the battery is disconnected. Gather all necessary tools (e.g., trim removal tools, screwdrivers, wire cutters/strippers).
- Access Existing Speakers: Carefully remove the door panels, dashboard grilles, or other trim pieces to access the factory speaker locations. Refer to your vehicle's service manual for specific trim removal instructions.
- Remove Factory Speakers: Disconnect the wiring and unmount the existing speakers.
- Install New Components:
- Tweeters (HS 24 MB1 EVO2): Install the tweeters in the designated factory locations, typically in the dashboard or door pillars. Connect them to the FWK TW crossovers.
- Mid-range Speakers (MS 100 MB1 EVO): Mount the mid-range speakers in their factory positions, often in the door panels. Connect them to the FWK W205 crossovers.
- Woofers (AX 08 MBL EVO / AX 08 MBR EVO): Install the woofers in the under-seat locations. Ensure correct left (MBL) and right (MBR) placement. Connect them to the FWK W205 crossovers.
- Wiring and Crossovers: Connect all speakers to their respective crossovers. The crossovers manage the frequency distribution to each speaker type. Ensure all connections are secure and properly insulated. Pay attention to polarity (+/-).
- Test System: Before reassembling the interior, reconnect the vehicle battery and test the audio system to ensure all speakers are functioning correctly and sound is balanced.
- Reassemble Interior: Carefully reattach all trim pieces and panels, ensuring no wires are pinched or damaged.
Note: Some users have reported that connectors for mid-range speakers may require slight modification or careful handling, and bass speaker connections can be stiff. Exercise caution during these steps to avoid damage.

Operation
Once properly installed, your Audio System MFIT W205 EVO speaker system operates in conjunction with your vehicle's existing head unit or aftermarket car audio system. The speakers are passive components, meaning they receive amplified audio signals from your car's amplifier (either built into the head unit or a separate external amplifier).
- Audio Source: Play audio from your preferred source (radio, media player, Bluetooth device connected to your head unit).
- Volume Control: Adjust the volume using your car's head unit controls.
- Sound Settings: Utilize your head unit's equalizer, balance, and fader controls to fine-tune the sound to your preference. The MFIT W205 EVO system is designed to deliver a balanced and powerful sound, but personal adjustments can further enhance your listening experience.
Maintenance and Care
To ensure the longevity and optimal performance of your Audio System MFIT W205 EVO speakers, follow these simple maintenance guidelines:
- Cleaning: Use a soft, dry cloth to gently wipe away dust from speaker grilles and surrounds. Avoid using harsh chemicals or abrasive cleaners.
- Avoid Moisture: While car interiors can experience some humidity, avoid direct exposure to water or excessive moisture. The speakers are not waterproof.
- Temperature Control: Protect the speakers from extreme heat or cold, which can affect material integrity over time.
- Secure Mounting: Periodically check that all speakers are securely mounted and that wiring connections remain firm. Vibrations from driving can sometimes loosen components.
Troubleshooting
If you encounter issues with your speaker system, refer to the table below for common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from one or more speakers | Loose wiring connection; incorrect polarity; faulty speaker or crossover; head unit/amplifier issue. | Check all wiring connections, especially at the speaker, crossover, and amplifier. Ensure correct polarity. Test with a known good speaker if possible. Verify head unit/amplifier is functioning. |
| Distorted sound | Volume too high; amplifier clipping; damaged speaker; incorrect crossover settings. | Reduce volume. Check amplifier gain settings. Inspect speakers for physical damage. Ensure crossovers are correctly wired. |
| Weak or unbalanced sound | Incorrect balance/fader settings; one speaker not working; phase issue. | Adjust balance and fader settings on your head unit. Check wiring for any disconnected speakers. Verify correct polarity for all speakers. |
| Buzzing or humming noise | Ground loop issue; interference from other electrical components; loose wiring. | Ensure all components are properly grounded. Check for any power wires running too close to audio signal wires. Secure all connections. |
If the problem persists after attempting these solutions, please contact customer support or a qualified car audio technician.
