Reshaping the auditory standards of luxury MPVs: Trumpchi GM 8 audio is deeply transformed to achieve a mobile concert hall

As a mid-to-high-end MPV that strikes a perfect balance between family warmth and business solemnity, Trumpchi GM 8’s original car audio system is often difficult to match car owners’ high standards for quality of life and professional image. This in-depth audio upgrade project,“Shaping the balanced sound field of the whole vehicle” and “strengthening low-frequency dynamics and hierarchy”Design goals for the core. Through the precise combination of selected top-of-the-line audio equipment, and the application of industry-leading acoustic technology and millimeter-level tuning calibration, we aim to create this multi-functional car with a professional concert hallImmersive Mobile Hearing TempleMake every trip an exclusive journey that pleases the senses.

【In-depth analysis of systematic upgrade plan】

 

1. The soul of the front sound field: Biwei “Black Core” series set (professional customized acoustic cabinet empowerment)

 

• Tweeter:The A-pillar inverted mold process is adopted for positioning and installation. Through the precise calculation of the installation angle and height, it is ensured that the sound waves reach the listener’s ears in the best path, so as to obtain extremely accurate sound image positioning and achieve extremely high separation and clear layering between human voices and musical instruments.

 

• Mid-bass unit:In view of the physical defects of the large cavity inside the original door panel and easy resonance, we tailored a professional wooden acoustic box for it. This measure fundamentally solves the problem of weak and turbid voice. With the support of the sealed box, Biwei’s “black core” mid-woofer unit can feel its dynamic response speed and sound densityLeapfrog lift (approximately 50%), the low frequency is strong and powerful, and the mid frequency is full and mellow, truly releasing the hidden soul and potential of this series of speakers.

 

2. Rear sound field and surround system: Feishi “Square Diamond” series set

 

In order to make up for the shortcomings of MPV models, such as generally weak rear sound field and blurred hearing, the rear sound field and surround system are selected from the Japanese Feishi “Square Diamond” series full-range package. Unique to this series of hornsDiamond Cut Textured Diaphragm Technology, making the high-frequency extension natural and transparent, and the mid-frequency vocals rich and emotional. The center channel and the rear surround channel are upgraded simultaneously, ensuring that every passenger in the car, especially the rear VIPs, can enjoy the “C-position” listening experience with clear positioning and rich details, which greatly enhances the sense of respect during business reception.

 

3. Ultra-low frequency system: American DB dual 6-inch subwoofer unit (hidden design)

 

In order to obtain excellent low-frequency performance without encroaching on the precious interior space at all, we adopted a hidden installation process and cleverly embedded a pair of American DB 6-inch subwoofer units into the trunk side wall. Accurately driven by a high-power Feishi P 1-2 single-channel power amplifier, this low-frequency system can provideExtremely deep, flexible and controllable divesThe low-frequency response, whether it is performing the majestic momentum of the symphony orchestra or restoring the rhythm of popular music, can be expressed with ease and freedom.

 

4. Drive core and audio source processing system

 

Power amplifier driver combination:The front sound field is driven by the powerful Feishi PE 6 six-channel power amplifier to ensure its abundant power reserve and control; The rear sound field is independently managed by a Feishi AP 4.75 four-channel power amplifier, realizing the refinement and independent adjustment of the power distribution of the front and rear sound fields.

Sound source optimization processing:The audio processing core of the system uses Japan’s Biwei professional DSP processor, which precisely processes each channel of the entire vehiclePhase Correction, Delay Alignment and Frequency Equalization, to build an accurate and wide sound stage. In the audio source part, Alpine A 09 professional lossless player replaces the original host machine, providing pure and high-resolution digital audio signals from the source, thus completely solving the fundamental sound quality bottleneck of insufficient signal quality of the original host machine.

 

【All-round modified effect listening experience】

 

• Family travel scenarios:The vocal performance brought by Biwei’s “Black Core” system in the front row is moist and emotional, making people deeply immersed in musical stories; The “square diamond” system in the back row provides balanced, full and clear sound field coverage for the whole family, making long-distance travel full of warm melody companionship.

 

• Business reception scenario:Thanks to the carefully tuned surround sound field and clean and powerful low frequencies, the car can create a quiet and enveloping theater-level auditory atmosphere. The details of the music are exquisite, and the dynamic retraction is calm and moderate. Its overall sound expression and delicacy are comparable to the sound systems of many million-level luxury flagship models.

 

Real feedback from car owners:“I never expected an MPV to create such an acoustic effect with a sense of’emperor’s position ‘! Business partners in the back row have repeatedly praised the extraordinary sound quality in the car, which undoubtedly adds a lot of points to our business image.”

 

【Music broadband customized audio concept】
“From the careful selection and matching of every piece of equipment, to the structural design of every acoustic box, to the process execution of every installation detail, the core goal of all our work is only one:At no expense, only for ultimate sound quality.”

Recommended suitable models:This system solution is especially suitable for medium and large MPVs and luxury commercial vehicles such as Trumpchi GM 8, GS 8, Buick GL 8, Century, Toyota Sienna, and Alphard that focus on the auditory experience of the entire vehicle passengers.
Professional advice tips:Biwei speaker units are extremely sensitive to cabinet volume, tightness and internal structure, which is the absolute key to their final performance. To ensure maximum return on investment,It is strongly recommended to choose an authorized store with extensive experience in Biwei modification and professional acoustic design capabilities for construction.
