Mercedes-Benz S500 W221 speaker upgrade and Bluetooth installation in Busan, South Korea. Improved sound quality and smartphone connectivity.
Revitalizing Your Mercedes-Benz S500's Sound
Is your cherished Mercedes-Benz S500 (W221 generation) sounding a bit tired? Many owners of these luxurious sedans, particularly those from 2009-2014, find that the original speakers begin to show their age. You might notice a 'flappy' or distorted sound, especially during bass-heavy tracks, or the speaker edges may appear worn. This degradation is a natural part of a speaker's lifespan, impacting your overall driving enjoyment. If your sound system isn't delivering the premium audio experience you expect from an S-Class, it's time to consider an upgrade. This review details a recent car audio upgrade performed in Busan, South Korea, focusing on speaker replacement and adding modern connectivity.
Speaker Upgrade and Installation Process
For this Mercedes-Benz S500 W221, the upgrade involved replacing the front speakers with PASC PI-165BL components and the rear speakers with PASC S12 models. The installation team opted for custom-made birch wood adapters for the mid-bass speakers to ensure a secure fit, alongside waterproofing measures. The tweeters were installed separately, creating a component system designed for balanced sound. This comprehensive speaker installation typically takes about 3 to 4 hours, though the exact time can vary based on the vehicle's specific condition and any additional services requested.
Installation Process:
- Careful removal of door panels and factory speaker assemblies.
- Fabrication and installation of custom birch wood adapters for new mid-bass drivers.
- Installation of waterproofing barriers behind the new speakers.
- Mounting of new component tweeters in the original locations.
- Connection of new speakers and testing of audio output and balance.
- Reassembly of door panels.
Adding Modern Connectivity: Bluetooth and AUX
A common limitation of the W221 S500 is the lack of built-in Bluetooth audio streaming, even if phone connectivity is present. This means enjoying music directly from your smartphone can be inconvenient. However, a simple yet effective solution is to utilize the AUX input. By connecting a Bluetooth receiver to the AUX port, you can seamlessly pair your smartphone wirelessly. This allows for high-quality audio streaming through your upgraded car audio system, transforming your listening experience without complex modifications. This Bluetooth integration is a quick process, instantly enabling you to play any music from your phone.
Additionally, the S500 received a wide-angle mirror replacement for the side mirrors. The stock mirrors have a narrow field of reflection, creating significant blind spots that can be hazardous during lane changes or parking. The wide-angle mirrors dramatically expand the driver's field of vision, significantly reducing blind spots and enhancing overall driving safety. This mirror upgrade typically takes around 30 minutes.
