Kia Carnival Hi-Limousine Audio Upgrade Review

Elevating the Kia Carnival Hi-Limousine Experience with Premium Audio

The Kia Carnival Hi-Limousine is a popular choice for its spaciousness and comfort, but its factory audio system can leave audiophiles wanting more. This review details a comprehensive car audio upgrade performed on a Kia Carnival Hi-Limousine, transforming its soundscape with high-end components. The goal was to surpass even the premium KRELL sound option, delivering a luxurious listening environment that complements the vehicle's premium feel.

BLAM Speaker System Installation and Sound Enhancement

The centerpiece of this audio overhaul is the installation of a premium 3-way speaker system from the French brand BLAM. The mid-woofer units were expertly fitted into the factory speaker locations using custom-made birch wood mounts for a perfect fit. Tweeters and mid-range drivers were precisely installed in the A-pillars, with custom angling to optimize sound dispersion. The A-pillar trim was then finished with the same material as the vehicle's interior, ensuring a factory-like appearance.

Before installation, meticulous masking was performed to protect the vehicle's interior. Door sound deadening was a crucial step, utilizing CSM sound-deadening mats to maximize vibration reduction. This dual-layer matting was applied to both the inner and outer door panels, adhering perfectly to the metal to effectively suppress vibrations. This process not only enhances sound quality by reducing resonance but also contributes to a quieter cabin.

Installation process:

1. Surface Preparation: Thoroughly clean and degrease the interior door panels to ensure optimal adhesion of sound-deadening materials.
2. Sound Deadening Application: Apply CSM sound-deadening mats to the inner and outer door skins, pressing firmly to eliminate air bubbles and ensure complete contact.
3. Speaker Mounting: Install custom-made speaker mounts and then securely fit the new mid-woofer drivers into the factory locations.
4. A-Pillar Customization: Fabricate and install custom A-pillar pods for the tweeters and mid-range drivers, ensuring precise angling for optimal sound staging.
5. Wiring and Integration: Connect all new speaker components and amplifier, ensuring all connections are secure and properly insulated.

Amplifier and Subwoofer Integration for a Complete Sound Stage

To complement the upgraded front speakers, a subwoofer was installed, designed to occupy minimal trunk space for maximum practicality. The factory amplifier was upgraded using a 12-channel Helix DSP unit from Germany, renowned for its precise sound tuning capabilities. Additionally, a 2-channel Focal amplifier was added specifically to power the subwoofer. The Helix DSP allowed for meticulous balancing of all speaker channels, creating a wide, immersive soundstage akin to a live concert hall.

The rear speakers were also upgraded as part of a 2-way system, utilizing a combination of Focal and BLAM components. Similar to the front doors, the rear doors received thorough sound deadening and vibration dampening treatment. All installations were performed using methods that allow for 100% reversibility, with enclosures secured using factory bolt points for a clean and professional finish. A custom grille was fabricated for the Focal FLAX EVO subwoofer, enhancing its aesthetic appeal.

This extensive car audio upgrade, including speaker upgrade and amplifier installation, transforms the Kia Carnival Hi-Limousine into a mobile concert hall. The result is a rich, detailed, and powerful sound system that significantly enhances the driving experience. While the specific cost in Korean Won was not detailed, similar comprehensive sound system upgrades in the US can range from $1500 upwards, depending on the components chosen.
