Mercedes S-Class W222 – Hi-End Car Audio ESB & Zapco | Plug & Play Installation with Custom Adapters, Comfort Mat Soundproofing

Mercedes S-Class W222 – Hi-End Car Audio ESB & Zapco + Comfort Mat Soundproofing

The Mercedes S-Class W222 is a flagship luxury vehicle equipped from the factory with the Burmester sound system. While it offers good overall sound quality, it still falls short of the expectations of drivers looking for true hi-end car audio performance. In this project, we carried out a complete audio upgrade based on ESB Audio speakers and Zapco electronics, combined with full Comfort Mat soundproofing, while preserving a fully OEM interior appearance.

The installation was carried out in a plug&play standard, but without using ready-made plug&play speaker kits. Instead, we designed and produced custom 3D-printed adapters specifically for the Mercedes W222. This approach allowed us to install full hi-end audio components without any modification to the factory wiring.

The additional Comfort Mat soundproofing significantly improved the vehicle’s acoustic environment, reducing noise levels and creating optimal conditions for a high-end audio system.

Mercedes S-Class W222 Soundproofing – Comfort Mat (doors, trunk, floor)

An essential part of the audio upgrade in the Mercedes S-Class W222 was comprehensive vehicle soundproofing using Comfort Mat materials. The goal was not only to reduce overall noise levels, but above all to create stable and controlled acoustic conditions for a true hi-end car audio system.

The soundproofing process covered the front and rear doors, trunk, rear bulkhead and floor. By applying Comfort Mat butyl damping materials, we significantly reduced panel vibrations, improved structural rigidity and minimized external noise entering the cabin.

Speakers – front, rear, center channel and bulkhead subwoofers (ESB Audio + Morel)

In the Mercedes S-Class W222, we carried out a complete loudspeaker upgrade: a 3-way front stage, 2-way rear stage, a dedicated center channel, and two 20 cm subwoofers integrated into the rear bulkhead. The system is based on ESB Audio components and a Morel center speaker.

All components were installed using a plug&play installation standard, but without using ready-made plug&play speaker kits. Custom 3D-printed adapters allowed us to install full hi-end components without any modification to the factory Burmester wiring.

Fiberglass spare wheel well enclosure – ESB Audio 3.10D4 subwoofer

A key part of this project was the creation of a custom fiberglass subwoofer enclosure integrated into the spare wheel well. This solution allowed us to preserve the full functionality and usability of the trunk in the Mercedes S-Class W222, while delivering significantly improved low-frequency performance compared to the factory system.

The enclosure houses an ESB Audio 3.10D4 subwoofer, a 250 mm driver designed to perform exceptionally well in compact, precisely calculated enclosures. The entire structure was hand-built – from the fiberglass mold, through final shaping, to finishing and integration with Comfort Mat soundproofing.
