How high-end are car stereo modifications? Here it is! Decrypting Porsche Cayenne modified Betway Audio 6 decoding system

 

In the atmosphere of car audio modification, people have heard of many large-scale system modifications of various brands, but few have actually heard of super systems. After all, the main player of car audio, financial resources determine the dominant position, and secondly, the modification shop must have strong technical strength. Generally speaking, if you have money, you have to find a powerful modification shop for modification, so as to truly reflect the timbre charm and the soul of music emitted by the large system.

This time we received a new Porsche Cayenne audio modification. It is not an exaggeration to describe the owner’s obsession with music as “fascinating”. Car owners not only love music, but also have a high pursuit of music quality. Car owners have always been optimistic about Japan’s Biwei, a high-end car audio brand. Japan’s Biwei audio system does not have a high demand for current, and the weight of the equipment is also very light, integrating the current product line with the highest acoustic technology. Of course, car owners of such an excellent brand understand that they should also find a modification shop with strong technical strength for modification. The music broadband modification shop is a professional shop specializing in modification of Biwei audio in the local area, and many modification cases have won the conviction of car owners. Through our communication and judgment, the car owner finally decided to choose the highest-end system of Biwei Audio, which consists of 6 mono audio decoders, 6 power amplifiers, 6 speaker units, and 6 power managers to form a super system.

Sound source modification part

Sound source selection is carried out by the Biwei STATE MM-1 DR top-of-the-line 24 Bit player, with linear PCM playback (studio sound quality processing standard). At the same time, it is also a high-fidelity ML boundary surface with the function of reversing rear view image, which is specially designed for the high-interference environment in the car. In terms of material selection, it is composed of 8 layers of precision German Schott optical glass and ultra-lightweight MAGNEOLA magnesium alloy patented shell. MAGNEOLA material minimizes electronic vibration interference, and the reading design without mechanical pure electronics solves the innate earthquake resistance problem of traditional CD players.

Let’s share the modification process of the entire system below, starting with the box modification of the front sound field door panel horn. Why should the door panel be modified into a box? It is a requirement for Biwei speaker units, and the box data must be official. First of all, the Biwei speaker has an off-axis eccentric design. In layman’s terms, the sound of the speaker unit is directional, that is, the sound of the speaker only propagates in one direction. This acoustic design is to reduce the propagation loss of sound frequency, because the Biwei midrange unit covers a frequency band within 40 HZ-1000 HZ. The wide frequency band, sound pointing design and the modification requirements of independent cabinets improve the working efficiency of each speaker unit to the best level. Therefore, the modification of the Biwei system is a systematic project that can best test the modification technology.

The shape and volume requirements of the box are designed, and the plate is cut by CNC, so that the data is more accurate.

Finally, apply a layer of waterproof and anti-corrosion material.

The Biwei tweeter unit adopts a specially configured tweeter cabinet and is made of magnesium alloy. The treble modification is relatively less complicated than the midrange cabinet of the door panel. However, the pointing adjustment of treble is still very technically difficult.

Rear trunk modification part

All the power-consuming equipment was modified in the rear trunk. In order to give this pile of expensive equipment a better place to live, the owner gave up the spare tire by considering it. Freeing up more ample space, the rear trunk of the new Cayenne seems to be born for audio modification. The flat rear trunk design saves more tedious work for modification.

The bottom plate is fixed without drilling or screwing.

The trunk equipment modification is designed to be divided into two layers. The power amplifier and power manager are placed on the bottom layer, six audio decoders are placed on the upper layer, the subwoofer cabinet is placed on the surface, and the battery installation position is cleverly designed in the middle.

In the production of terminal blocks, all contact points are not soldered at high temperature. This is to protect the wires, because high-end wires will undergo qualitative changes when exposed to high temperatures.

Wiring is a complicated and tedious process, and reasonable wiring layout will also play a certain role in sound quality and interference.

After covering the original cover, only a bass cabinet is exposed, which is the truest portrayal of low-key luxury. It also just fits the car owner’s low-key style of dealing with people.

After the modification was completed, a series of professional debugging work began, using the SIEG tuning system, a tuning equipment exclusively configured by Biwei.

 

After professional debugging, the effect produced by the system amazed the ears of every technical team present. The musical scene was so kind, charming and full of feelings. Every moving note was vivid, and the performance of every musical instrument was independent and did not disturb each other. The word “respect” is appropriately used here. The singer’s soul-stirring voice is rendered to every corner of the car, truly realizing the wonderful magic from hearing to touch.
