1. Vehicle Introduction
The BMW X3 offers excellent handling, a sporty and stylish appearance, a well-organized interior layout, comfortable and supportive seating, and high-quality materials with exquisite craftsmanship and good sound insulation. However, the factory audio system lacks depth and spatial quality, failing to meet the demands of owners seeking an ultimate music experience, prompting them to upgrade the audio system.
2. Configuration List
DSP Amplifier: DSP X12
3. Installation Process
Before the upgrade, a professional team used circuit testing equipment to check for electrical hazards, analyzed the acoustic characteristics of the vehicle’s interior with acoustic instruments, and measured the positions of the seats and speakers to develop a personalized plan.
During installation, the technician placed the DSP X12 under the driver’s seat, a location that saves space and is close to the original vehicle wiring, reducing signal loss. First, they secured the device with damping pads to prevent noise from vibrations. Then, they accurately connected the input lines to the original audio output, linking the output lines to each speaker unit, organizing and securing the wiring along concealed channels to avoid interference.
After installation, the technician used audio testing software and acoustic instruments to play various styles of music for tuning. They first calibrated the speakers with pink noise to ensure volume balance. For different music styles, they made targeted adjustments to the DSP X12 parameters to enhance the performance of each frequency band. Additionally, they adjusted the delay parameters based on the distance between the seats and speakers to create a surround sound effect, allowing the owner to immerse themselves in music from any position within the vehicle.
4. Modification Review
After the upgrade, the audio performance of the BMW X3 was significantly enhanced. Playing pop music, the singer’s voice was delicate and detailed; classical music showcased pure instrument tones with clear layers; rock music delivered a strong rhythm with impactful bass. From the installation perspective, the DSP X12 was installed in a reasonable position that did not affect the vehicle’s usability or aesthetics, with standardized wiring connections ensuring stable operation of the audio system and vehicle safety. This audio upgrade fully utilized the capabilities of the DSP X12, creating a high-quality mobile music space for the owner and greatly enhancing the driving experience.
