Kia Sorento MQ4 Car Audio Upgrade Review: PHASS Speakers

Why Upgrade Your Kia Sorento MQ4's Car Audio?

Many Kia Sorento MQ4 owners consider a car audio upgrade soon after purchase. As a popular family vehicle, the Sorento is often used for long drives and daily commutes, making a high-quality sound system crucial for enhancing enjoyment and reducing stress. While factory speakers provide basic sound, they often fall short in delivering nuanced audio separation and deep bass. This can lead to a less-than-satisfying listening experience and a desire for a more immersive sound.

PHASS Speaker Installation and Process

This particular Kia Sorento MQ4 received a comprehensive sound system upgrade, building on a previous front speaker enhancement. The owner, already impressed with PHASS audio quality, returned to upgrade the rear speakers. The process involved replacing the existing front speakers with the PHASS 165BL model, known for its wide frequency response and consistent sound quality across volume levels. The previous front speakers were repurposed for the rear doors.

The installation focused on meticulous execution to ensure optimal sound performance and durability. Speaker wiring was treated with sound-absorbing material to minimize interference and prevent rattles, contributing to cleaner audio signal transmission. To combat road noise and vibrations, the plastic door panels underwent sound-deadening treatment, which also enhances the speaker's ability to produce tight, impactful bass. Additionally, baffle foam was applied to seal the gap between the door trim and the speaker, preventing sound loss and further reducing trim rattles.

Recognizing that many Sorento models lack rear tweeters, this installation included custom fabrication to add them. This significantly improved the rear soundstage, addressing the common issue of a muffled or distant rear audio experience. The front speaker installation also saw the replacement of the wooden adapter and baffle foam with new components for a factory-fresh fit and finish.

Before and After: The PHASS Sound Difference

The upgrade to PHASS 165BL speakers in the front and the addition of rear speakers, including tweeters, transformed the Sorento's audio landscape. Listeners can expect a much more detailed and spacious soundstage, with clearer vocals and instruments. The low-end frequencies are more pronounced and controlled, providing a richer, more engaging listening experience. This comprehensive car audio upgrade ensures that both front and rear passengers enjoy a premium sound environment, making every drive more enjoyable.

The durability of this installation is enhanced by the sound-deadening and sealing techniques used. By minimizing vibrations and ensuring a proper speaker seal, the components are less prone to wear and tear from road conditions. Proper installation also means the sound quality will remain consistent over time, without the degradation often associated with poorly fitted audio systems.
