Upgrade your Mercedes-Benz W205 with a professionally engineered audio system using german MATCH & HELIX Components, expertly supplied, installed and calibrated by Luxury Auto House.

Designed specifically for the Mercedes-Benz C-Class platform, these plug-and-play upgrade packages deliver a dramatic improvement in sound quality while retaining the factory head unit, steering wheel controls, parking sensors, Bluetooth, navigation prompts and all original vehicle functionality.

Unlike universal aftermarket audio systems, every package has been developed exclusively for the W205 using vehicle-specific amplifiers, speakers, wiring harnesses and mounting hardware. This allows every component to integrate seamlessly with your Mercedes without cutting or modifying the factory wiring.

Whether you are looking for improved bass, greater clarity or a complete audiophile-grade sound system, we offer four upgrade levels for each factory audio system.

Every package includes professional installation, custom DSP tuning and full system calibration by our in-house audio specialists.
