Overview
Transform your Mercedes-Benz C-Class W206 factory audio system with the HELIX Ci3 Speaker, Subwoofer & DSP Amplified Package, a comprehensive sound upgrade designed to deliver improved clarity, stronger bass and a more immersive listening experience.
Developed for compatible Mercedes-Benz C-Class W206 vehicles equipped with the standard factory sound system (non-Burmester), this package combines HELIX COMPOSE Ci3 speaker technology, dedicated subwoofer upgrades and advanced digital signal processing.
Unlike a front-speaker-only upgrade, this package is designed to improve sound reproduction across the front and rear speaker positions, creating a more balanced listening experience throughout the cabin.
The HELIX Ci3 speakers are engineered for detailed music reproduction, helping improve vocal clarity, instrument separation and tonal balance.
Dedicated low-frequency drivers enhance bass depth and definition, while the DSP amplifier provides precise control over speaker equalisation, crossover frequencies, time alignment and individual output levels.
With professional DSP calibration, the complete system can be optimised for the Mercedes-Benz W206 cabin acoustics, delivering improved stereo imaging, controlled bass and a more refined sound signature.
The upgrade is designed around compatible factory audio equipment, retaining the original infotainment display and premium interior appearance.

Please Read Before Purchasing
This package is intended for Mercedes-Benz C-Class W206 vehicles equipped with the standard factory audio system, without Burmester sound.
Compatibility depends on the vehicle's production year, factory head unit, original amplifier architecture, speaker arrangement and wiring configuration.
This is a front and rear speaker, subwoofer and DSP-amplified package. It is different from the front-speaker-only version.
The exact speaker models, subwoofer models, amplifier, wiring harness and installation accessories must be confirmed against the package contents before ordering.
Vehicles equipped with the factory Burmester system require a different integration configuration.
Professional installation and DSP tuning are recommended. Installation and tuning are not included in the online product price unless expressly specified.
Who This Package Is For
This package is ideal for Mercedes-Benz C-Class W206 owners who want a comprehensive improvement over the standard factory audio system without replacing the original infotainment display.
It is particularly suitable for drivers seeking clearer vocals, improved instrument separation, stronger bass and a more immersive listening experience for front and rear passengers.
The DSP-amplified configuration is also suitable for customers who want their audio system professionally calibrated rather than relying solely on factory sound settings.
Installation & Tuning Notes
Installation involves upgrading the compatible front and rear speaker positions, integrating the dedicated low-frequency drivers and connecting the DSP amplifier to the factory audio system.
Before installation, the technician must verify the factory audio signal routing, speaker impedances, power requirements, connector compatibility and available amplifier integration points.
Professional DSP commissioning should include input signal analysis, channel assignment, crossover configuration, time alignment, equalisation, speaker polarity verification and subwoofer phase alignment.
The final calibration should be tailored to the Mercedes-Benz W206 cabin acoustics, original speaker positions and the customer's preferred listening experience.
