Unlocking the high-fidelity listening experience: Toyota Reiz is equipped with a rational upgrade solution for the German 0.3 frequency system

As our loyal customer for many years, Reiz owners entrusted us to complete the initial upgrade of the complete audio system for their cars a few years ago. With the continuous pursuit of high-quality music listening experience and the continuous improvement of appreciation, car owners have recently begun to think about how to further enhance the expressiveness of the sound system on the original basis. After learning that we have launched the high-profile German zero-point GZRC 165.3 SQ ATC three-way speaker package, the owner was immediately attracted by its excellent technical characteristics and sound quality potential, and paid the deposit without hesitation, formally confirming the upgrade plan of the core components of the system.

 

 

The following is a complete presentation of the detailed process and process details of this Reiz audio system core upgrade:

 

First of all, the “family photo” photo of all the core equipment involved in this upgrade is shown. The sound source part of the system is provided by the highly acclaimed Alpine A 09 high-end digital player to ensure the pure output of high-quality digital audio signals; The signal processing core is equipped with Magic Cube 8-channel DSP processor, which provides powerful digital frequency division, time calibration and fine tuning capabilities for the entire system. In the speaker drive part, a set of zero-point GZRC 165.3 SQ ATC three-way speakers will be driven by a Magic Cube six-channel power amplifier in active split mode, ensuring that each unit receives independent and optimized power supply. It is worth mentioning that the DD brand subwoofer system previously upgraded by the owner has been completely retained due to its excellent performance, and continues to be responsible for the rendering and supplement of the low-frequency part.

The first step in construction is to carefully remove the front soundstage rainbow horn, which has been in service for nearly three years. Despite years of use, the removed speaker unit is still as bright as new, with no signs of rust or aging. This just confirms the rigor of professional modification in material selection, installation technology and waterproofing treatment, and is an intuitive embodiment of the long-term reliability of modification quality.

 

Install the new zero-point three-way system mid-woofer unit. We have customized our exclusive waterproof gasket for it and carried out strict sealing treatment. After installation, the effect is neat and stable, providing an ideal foundation for the best performance of the horn.

The key to sound field positioning-A-pillar inverted mold modification. Through precise positioning and shaping, the zero-point treble and midrange units are integrated into the A-pillar at the best pointing angle, laying a physical foundation for creating a wide and accurate sound stage.

According to the owner’s individual usage habits, we cleverly installed the control panel of the Alpine A 09 player in its designated and easy-to-operate center console area.

Overall layout effects at a glance. All modified parts are highly integrated with the vehicle interior, reflecting the concealed, clean and professional modification concept.

 

Installation of power amplification and processing core. The Magic Cube six-channel power amplifier and its matching 8-channel DSP processor are integrated and installed in the bottom space of the passenger seat, which has a compact layout, good heat dissipation, and does not occupy the seating space at all.

Installation of sound source host and subwoofer amplifier. The main body of the Alpine A 09 host unit and the German Lesden bass amplifier that drives the retained DD bass are properly placed at the bottom of the main driver’s seat to achieve weight balance and efficient space utilization.

Finally, a brief summary of the sound quality effect after this Reiz audio upgrade is made: the overall sound performance of the system has achieved a qualitative leap. The image of vocal singing and musical instrument performance is full and solid, and the sense of density is significantly improved; The rich details in the music are as legible as grains and layered. Thanks to the active precision drive of the six-channel power amplifier to the three-way unit, the connection between the high, medium and low frequency bands is natural, the transition is smooth and smooth, and the rhythm response is accurate and consistent. This upgrade not only gives this Reiz’s sound system a new look, but also turns every trip into a pleasant “wise” listening enjoyment.
