Artz upgrades Rainbow three-way and Stinger power supply

Mazda Atez owners have previously completed the initial upgrade of the entire car’s audio system in other stores. However, with the continuous improvement of their ability to appreciate sound quality, the original system configuration can no longer meet their increasingly sophisticated hearing needs. In order to achieve a more delicate level and more accurate restoration, the owner decided to carry out an in-depth upgrade: the original two-way system was fully upgraded to an active three-way architecture. After careful evaluation and recommendation by the professional team, the main sound field finally selected the German Rainbow SL-C 6.3 Pro three-way speaker, which is famous for its accurate phase performance and rich detail restoration ability. The original power amplifier in the system is retained and continues to drive this new speaker unit, while the original DSP power amplifier all-in-one machine is replaced by Magic Cube eight-channel professional audio processor to provide purer signal processing and finer channel independent adjustment ability. As for the original bass system, because its performance still meets the requirements, it will continue to play the role of consolidating the low-frequency foundation in the system.

This upgrade integrates a total of three high-power amplifiers working at the same time, posing a severe test to the power supply of the whole vehicle. We must be soberly aware that the power supply is the fundamental source of energy in the sound system, and the power amplifier is essentially a process of converting electric energy into sound energy. If the power reserve is insufficient and the voltage is unstable, it will directly lead to the power amplifier being unable to output at full capacity, dynamic compression, loss of details, and even audible distortion. Therefore, we strongly recommend and assist the owner to install a special battery for American Stinger audio. This upgrade is by no means dispensable. It can significantly improve the problem of bass drag and untight retraction caused by tight power, and make the low frequency compact and flexible; At the same time, sufficient power supply can also make the extension of high frequencies more distant and natural, and the overall sound quality presents higher transparency and more delicate texture, which can be described as killing multiple birds with one stone.

 

Car audio modification is a precise integration of art and technology. Excellent equipment is only the foundation, and the ultimate modification technology and scientific acoustic adjustment are the real key to transforming semi-finished equipment into complete works of art. Below, we will show the whole process of this system from installation to molding through detailed details. The rigorous attitude and professional standards contained in it are the reliable guarantee of high-quality sound.

 

The core of this upgrade-German Rainbow SL-C 6.3 Pro three-way package speaker. Its tweeter unit is bright but not harsh, the midrange is full and rich, and the mid-bass is calm and solid, providing an ideal unit foundation for active split gameplay.

The inversion and positioning of the A-pillar is the core link to build the soul of the sound field in car audio modification. Different installation angles and heights will directly affect the sound propagation path, reflection point and final sound field image. Based on years of practical experience and acoustic measurements, we set unique pointing angles for the treble and midrange units. This kind of “pointing” is not the same, but the result of personalized calculation and simulation of the interior space and driver’s listening position of the Atez model. Precise pointing aims to create an “emperor’s position” sound field with excellent height, depth and width. The “sense of presence” in which musical instruments and vocals seem to be separated from the car body and vividly arranged in front of your eyes is the soul pursued by top car audio systems.

The overall effect after the A-pillar inverted mold is completed. The covering process is highly integrated with the texture and color of the original car interior, achieving the perfect combination of visual harmony and acoustic function.

The midwoofer unit at the door panel is installed to complete the effect. In addition to the stable installation, we also pay attention to the sound insulation, shock absorption and sealing treatment inside the door panel, aiming to create an ideal working environment for the speaker, reduce unnecessary resonance and acoustic short circuit, and release the potential of the unit.

The trunk is a common location for installing power amplifier equipment. We have installed two power amplifiers and a Magic Cube DSP audio processor here in a centralized and orderly manner. The layout not only considers the convenience of heat dissipation and maintenance, but also pays more attention to the standardized wiring of wires and the avoidance of signal interference. All wiring is firm and clearly marked, which reflects the cleanliness and professionalism of the back-end system.

The digital audio source playback host originally installed by the owner has been retained. As a high-quality digital signal source, it will continue to provide high-resolution music files for the system.

Safety is the first principle of modification. We have equipped the newly added Stinger battery and power amplifier system with high-quality power cords with sufficient current carrying capacity, and installed high-current safety-compliant safety holders near the positive output end of the battery to ensure safe electricity consumption.

The American Stinger SPV 70 audio-specific battery is skillfully installed under the main driver’s seat. This location not only saves space, but also is easy to connect. Its powerful storage and discharge capabilities will become the energy cornerstone for the stable and powerful operation of the entire sound system.

 

This in-depth upgrade of Mazda Atez’s sound system has come to a successful conclusion. Even through the samples recorded by mobile phones, you can initially feel that the sound field is significantly widened, the image of human voices and musical instruments is clear and stable, the overall timbre is balanced, and the overtones are rich and natural. With the assistance of professional spectrum analyzers and other tools, the final adjustment achieves a high balance of energy distribution among high, medium and low frequencies. This sense of balance is the key to whether the advanced sound system is “listening” or not-it has no excessive stimulation of a certain frequency band, which can make people immerse themselves in music for a long time without feeling tired, and truly restore the original intention of music creation.
