Hyundai Grandeur HG Speaker Upgrade Review

Revitalize Your Ride with a Hyundai Grandeur HG Sound System Upgrade

Is your Hyundai Grandeur HG's audio system sounding a bit tired? Many owners find that as a vehicle ages, the desire for a refreshed interior experience grows. While aesthetic changes are common, the driving experience is profoundly impacted by sound. If you're feeling underwhelmed by your car's audio, a car audio upgrade, specifically a speaker upgrade, can breathe new life into your daily drives. This review details a recent sound system upgrade for a Grandeur HG, transforming its auditory output and enhancing overall enjoyment.

Stock speakers are functional but rarely deliver the rich, detailed sound many audiophiles crave. Replacing them with high-quality aftermarket units, like the PHASS speakers used in this installation, can create an immersive listening environment, akin to a live concert. This type of upgrade not only elevates the car's value but also makes every journey more engaging.

Optimizing Sound with Speaker Tuning and Soundproofing

To achieve the best possible audio performance for the Grandeur HG, the installation included not only a front speaker replacement but also door trim soundproofing and damping. The quality of the installation is as crucial as the components themselves for maximizing the efficiency and impact of the new speakers. This custom approach ensures the speakers perform at their peak.

The front speakers, comprising 6.5-inch mid-bass units, were chosen for their ability to produce both powerful and nuanced sound. To ensure stability and minimize vibrations, custom-made birch wood adapters were utilized. This is essential for maintaining optimal sound quality.

Installation Process:

1. Remove the factory speakers.
2. Install the new PHASS 2-way speaker system, mounting the mid-bass drivers in the door panels and tweeters in the dashboard.
3. Apply RS butyl sound-deadening pads to the door panels to reduce vibrations and resonance.
4. Install 3M D3 Thinsulate sound-absorbing material to further enhance cabin quietness and audio clarity.
5. Precisely mount the new PHASS tweeters into the dashboard, often requiring custom grille work for a clean, integrated look.

The soundproofing process is vital. By applying damping materials like RS butyl pads to the door panels, vibrations generated by the speakers are significantly reduced. Complementing this, 3M D3 Thinsulate is used for sound absorption, minimizing external noise intrusion and improving the clarity of the in-cabin audio.

Installation Time and Cost Considerations

This comprehensive car audio installation, including speaker upgrades and soundproofing for a Hyundai Grandeur HG, typically takes around 3 to 5 hours to complete. The exact duration can vary based on the specific vehicle condition and any additional custom work requested.

In Korea, the estimated cost for this type of speaker tuning and soundproofing service ranges from approximately 90,000 to 130,000 KRW, which translates to roughly $75 to $115 USD. This price reflects the quality of components used and the labor involved in a professional installation. While this review focuses on a specific installation in Korea, similar services are available globally, with costs varying by region and the specific parts chosen for your car audio system.
