1. Vehicle Introduction
The Hongqi HQ9, as a high-end luxury MPV, offers spaciousness and comfort, creating a quiet cabin with excellent sound insulation. However, the original car audio quality is poor, with a flat sound lacking in depth, failing to meet the owner’s pursuit of high-quality music, leading to a strong demand for audio upgrades.
2. Configuration List
DSP Amplifier: DSP F68
3. Product Features and Installation Process
The DSP F68 boasts powerful features, including 4 high-level channels and 2 low-level inputs, allowing stable connection to the original car audio for high-quality signal acquisition. It has built-in Bluetooth 5.0 for easy connection to smart devices. Its 8 low-level outputs and 6×80W power provide ample power for the speakers. With a frequency response of 20Hz – 20KHz, it restores full-range sound. The 31-band parametric equalization can compensate for uneven frequency response in the complex acoustic environment of the car; precise delay adjustment can create surround sound based on the distance between seats and speakers.
4. Modification Review
After the upgrade, the audio effect of the Hongqi HQ9 has significantly improved. In pop music, the singer’s voice is delicate and realistic; in classical music, the instrument tones are pure and layered; in rock music, the rhythm is strong, and the bass is impactful. From the installation perspective, the DSP F68 is installed in a reasonable position that does not affect the use and aesthetics of the interior, with standardized wiring connections ensuring the stability of the audio system and the safety of the vehicle. This upgrade has created a high-quality music space for the owner, greatly enhancing the driving experience.
