Mercedes-Benz GLA 45 AMG Speaker Upgrade Review

Mercedes-Benz GLA 45 AMG: Performance Highs, Audio Lows

The Mercedes-Benz GLA 45 AMG is a powerhouse of performance, delivering exhilarating driving dynamics. However, many owners find the in-car audio experience lacking, especially when compared to the vehicle's premium status and price point. The factory-installed speakers often feel like a cost-saving measure, failing to match the car's overall caliber. This is where a specialized speaker upgrade for the GLA 45 AMG becomes a compelling proposition for discerning drivers.

This guide explores the common issues with the stock audio system in the GLA 45 AMG and details a real-world installation of a speaker upgrade at Today's Car Namyangju, showcasing the transformative impact on sound quality.

Addressing the Weaknesses of Stock GLA 45 AMG Speakers

A closer look at the original speakers reveals a surprisingly basic construction, inconsistent with the vehicle's luxury and performance. Typically featuring a plastic frame and a small magnet, these units struggle under higher volumes, leading to distorted sound and muddy bass. This is the root cause of the audio dissatisfaction many GLA 45 AMG owners experience. Sound reproduction relies on speaker cones vibrating; when the factory unit's frame is weak, the door panel itself vibrates, creating unwanted resonance and compromising clarity. A true audio upgrade requires more than just swapping speakers; it necessitates enhancing the door's structural integrity and sound deadening.

The Mercedes-Benz GLA 45 AMG Speaker Upgrade Process

The process begins with meticulous masking to protect the premium interior surfaces of the GLA 45 AMG, a crucial step for high-end vehicles. The door panels are then carefully removed to expose the factory speaker and the underlying door structure.

Installation Process:

1. Door Panel Removal and Inspection: The door trim is carefully detached, revealing the stock speaker. The factory unit's limitations, such as its small magnet and basic construction, are evident, highlighting its inability to produce detailed mid-range and high frequencies or robust bass.
2. Sound Deadening Application: Before installing new speakers, extensive sound deadening material is applied to the inner door skin. This critical step reduces panel resonance, enhances structural rigidity, and creates a more controlled environment for the speaker, significantly improving mid-bass response and overall clarity. This stage is vital for maximizing the potential of any new speaker system.
3. MUSEWAY MGK165 Mid-Woofer Installation: The MUSEWAY MGK165 mid-woofers are installed using custom-designed, vehicle-specific adapters (in this case, birch wood adapters for Mercedes-Benz). These adapters ensure precise mounting angles and depth, which are crucial for optimal sound staging and imaging. The MGK165 features a large magnet and a double-edge surround, designed to deliver deep, impactful bass while maintaining clear and articulate mid-range frequencies, particularly for vocals.
4. FastRing Installation: A FastRing is applied around the speaker to seal the gap between the speaker and the door panel, preventing sound leakage into the door cavity and directing all the sound energy into the cabin for improved efficiency and focus.

The result is a significantly improved audio experience, characterized by crisper highs, clearer vocals, and a much tighter, more defined bass response, transforming the GLA 45 AMG's cabin into a more enjoyable listening environment.
