Military-grade modification technology Audi Q 7 audio modification Japan’s Biwei audio Aiwei top power amplifier

The collocation of car audio modification equipment is also very particular. We strive for the principle of simplicity and simplification, and the selection of equipment should be as precise and simple as possible. From the perspective of HiFi, once the sound system becomes complicated, it will not only increase the cost, but also have a certain impact on the effect. Many music lovers have a misunderstanding that the more speakers, the better the effect, such as three-way frequency, four-way frequency, etc. In fact, the best speaker is coaxial, but the manufacturing technology cost is high. Due to the limitation of space inside the car, the most suitable one is the two-way unit.

The following introduces a case of an Audi Q 7 modified Japanese Biwei two-way speaker. The owner usually mainly listens to pop songs, English songs, and occasionally needs rock music to set off his inner passion. For this listening style, it is the best solution to choose Biwei A series two-way frequency, which is paired with Aiwei’s top four-channel power amplifier driver, creating a super high cost performance; The subwoofer system uses 0.8-inch bass and zero two-channel power amplifier; The system is equipped with Biwei pure dsp eight-channel output.

 

Aiwei’s four-channel flagship power amplifier meets HiFi standards in terms of appearance and sound quality. The output power reaches 160 watts per channel. While high power, the sound performance is delicate and soft, and the dynamic performance of the sound line is very balanced.

This is a family photo of the equipment that needs to be modified. Due to the requirements of the owner, all the units of this modified Biwei speaker are installed in situ, and the effect will be reduced a little if the modified box is not used. However, Biwei speaker has the core technology of acoustic eccentric pointing, which can easily kill most big brand speakers.

The following is the detailed operation process of the modification, Biwei A 130 III unit modification.

First install the customized speaker pad and apply sealant. The benefits are waterproof, sealed to prevent air leakage, and earthquake-resistant.

It does not affect any use space, and the bass effect is very good. The low frequency is clean and elastic, with rich diving depth and sufficient low volume feeling.

 

Two power amplifiers and one dsp are all installed under the rear seats. Here are the details of the modification process…

 

 

All equipment wiring adopts professional-grade terminal blocks, and it is a standard for professional modification to eliminate welding.

The installation and wiring of Aiwei’s top four-channel power amplifier are completed.

The zero-point bass amplifier and Biwei dsp wiring are installed.

Renderings of the overall layout modification completed.
