1. Current Status of the Model
The Lexus ES300H is highly favored in the luxury sedan market due to its comfortable driving experience and excellent quietness. However, the original car audio system has shortcomings in audio signal processing, resulting in a flat sound that lacks spatial depth, making it difficult to leverage the advantages of the quiet cabin environment. This has led to an urgent demand for audio upgrades among owners who pursue high-quality music.
2. Configuration List
Audio Processor: DSP X12
3. Installation Process
Before installation, the technician uses professional circuit testing tools to conduct a detailed inspection of the vehicle’s electrical system, checking for potential short circuits and open circuit hazards to ensure electrical safety. Given the compact size of the DSP X12, it is installed under the driver’s seat, saving space and facilitating connections to the original car wiring. During wiring, the technician uses high-quality shielded audio cables, connecting one end to the output port of the original car audio host and the other end to the DSP X12, ensuring stable audio signal transmission and reducing interference. Additionally, the power line is connected to the vehicle’s battery, with proper insulation and securing measures taken to ensure stable power supply to the device.
4. Tuning and Optimization
After installation, the technician uses professional audio tuning software to play different styles of music and tune the DSP X12. By adjusting the 31-band EQ equalization and channel delay parameters according to the acoustic characteristics of the cabin space, the sound effect is optimized. When playing jazz, the mid-high frequency expressiveness is enhanced to highlight instrument details; when playing pop music, the bass is reinforced to create a dynamic atmosphere.
5. Upgrade Effects
After the upgrade, the audio effect of the Lexus ES300H is significantly improved. The DSP X12 optimizes the audio signal processing, resulting in a richer sound layering and stronger spatiality. When playing classical symphonies, the sounds of various instruments are clearly distinguishable and accurately positioned, as if one is in a concert hall; when playing vocal songs, the singer’s voice is reproduced clearly with delicate emotions. The cabin creates an immersive musical atmosphere, significantly enhancing the driving experience.
