Mercedes-Benz GLE Car Audio Upgrade Review

Is the Stock Burmester System Truly Enough?

Are you driving a Mercedes-Benz GLE W166 and feeling underwhelmed by its audio performance, despite the vehicle's luxury status? Many GLE owners share this sentiment. While the factory Burmester system offers a decent listening experience, it often falls short in terms of sound resolution and soundstage depth. This review details a real-world speaker upgrade for the GLE, demonstrating how to elevate your in-car audio to a new level.

Stock Speakers vs. Premium Aftermarket: What's the Difference?

The limitations of the Burmester stock system become apparent upon closer inspection. For instance, the stock mid-woofer reveals a smaller, lighter magnet structure compared to premium aftermarket options. This design can lead to a loss of resolution, especially in mid and high frequencies, and requires higher volume levels to achieve clarity, resulting in a sound that lacks detail.

Premium aftermarket speakers, such as the PHASS brand used in this installation, feature a fundamentally different construction. They boast a substantial magnet assembly, robust rear housing, and carefully selected diaphragm materials. This engineering results in detailed mid-range frequencies and accurate sound imaging, making vocals and instruments sound significantly more lifelike, even at moderate volumes.

Speaker Construction Dictates Sound Quality

A larger and heavier magnet provides superior control over the speaker cone's movement, leading to more precise sound reproduction. The cost-saving measures in the stock Burmester system, utilizing smaller magnets, inevitably cause signal loss and reduced clarity, particularly noticeable in the higher frequency ranges.

GLE Speaker Replacement: The Installation Process

This project involved a comprehensive replacement of the door speakers in a W166 GLE. The mid-woofers and tweeters in both front doors, along with the subwoofer, were upgraded. Due to the unique speaker dimensions in the GLE, custom brackets are essential for a secure and optimal fit.

From Door Panel Removal to Wiring

The installation begins with carefully removing the lower door panel to access the stock mid-woofer. After removing the original component, the space is prepared for the new speaker, and sound-deadening material is applied extensively. It's often said that up to 70% of sound quality improvements come from meticulous installation and acoustic treatment.

The material consistency of premium speakers is crucial. The diaphragm material, magnet configuration, and rear enclosure all influence acoustic performance. The PHASS mid-range drivers used here feature a distinctive gold-colored rear finish, which is not merely aesthetic but indicative of the sophistication of their acoustic design.

Enhanced Low Frequencies with a Dedicated Subwoofer

Door speakers alone often struggle to reproduce deep, impactful bass. This upgrade included the installation of a dedicated subwoofer using a custom-fit bracket. This allows the mid-woofers and the subwoofer to operate within their optimal frequency ranges, contributing to a richer and more immersive overall soundstage.

Beyond Sound: Aesthetic Upgrades with Ambient Lighting

Audio tuning isn't solely about sonic performance. Integrating ambient lighting with the door tweeters adds a captivating visual element, enhancing both the "sight" and "sound" experience. This installation incorporated blue ambient lighting into the door tweeters and the existing Burmester speaker grilles.
