The pinnacle reshaping of the listening experience: Logo 308 car audio system is fully upgraded with 0: 3 active configuration

The person who came to upgrade this time was a car owner with the logo 308, who has the pursuit of continuous improvement in the listening quality of music. Earlier, he had completed the preliminary modification of a two-way audio system with us, but with the accumulation of listening experience and the continuous improvement of listening requirements, he felt that the existing system still had considerable room for improvement. In order to obtain more delicate and accurate sound performance, he decided to choose us again for in-depth upgrades. This choice is also based on trust in our technical strength, and considering the convenience of tuning and after-sales service in the future, nearby processing will undoubtedly provide long-term and stable guarantee for the audio status of your car.

Regarding the selection of core components for this upgrade, after careful listening and comparison, the owner finally chose the Ground Zero three-way speaker set with accurate sound restoration and distinct layers to replace the previously modified Focal two-way speaker set. frequency system. We provided it with professional depreciation recovery services and successfully disposed of the original Jinlang horn. In the subwoofer part, the owner originally installed a Rockford Fosgate entry-level 10-inch subwoofer. During the upgrade and debugging process, we specially compared it with the 8-inch subwoofer at zero point in detail. The actual listening experience is significantly different: the zero 8-inch subwoofer shows an unusually clean low-frequency response, has a better dive depth, and can reach lower frequencies. At the same time, the volume and texture of low frequencies have also been comprehensively improved, and the overall performance is more Full and full of control. After this intuitive comparison, the owner decided to replace it with zero-point subwoofer without hesitation, and we also recycled the original Laifu bass products by depreciation.

The final upgrade scheme has been carefully planned, and the specific configuration is as follows: In order to realize the active split-sound driving mode of 0-point 3-way speakers and ensure that each speaker unit can obtain independent and optimized signals and power, the system needs to add a two-channel power amplifier. For this reason, we recommend a zero point two-channel power amplifier, which is specially responsible for driving the middle and bass unit in the three-way system to provide abundant and stable power. An Alpine four-channel power amplifier previously modified by the owner was fully utilized to drive the midrange and tweeter units in the three-way system. The digital audio processor (DSP) continues to use the Alpine 8-channel DSP installed during the previous modification, and uses its powerful tuning ability to accurately manage the signals in each frequency band, so as to achieve fine adjustment of sound field positioning, delay and frequency characteristics.

The following is a detailed record of this modification process, as well as physical pictures of all the upgraded equipment that needs to be installed for a clear understanding.

The A-pillar of the door is the key position for installing the treble and midrange units, and its angle and height directly affect the width, height and image accuracy of the sound field. We are carrying out professional A-pillar inverted mold positioning work to ensure that the horn installation position meets the best acoustic pointing requirements.

After careful covering and technological treatment, the modification of the A-pillar midrange and tweeter units has been successfully completed. The final effect not only meets the acoustic standards, but the craftsmanship level of its integration with the original car interior also reflects the high-quality modification aesthetics.

This is the Alpine four-channel power amplifier that the owner has installed in the previous modification. It has stable performance and continues to be entrusted with the important task of driving the middle and treble in this upgrade.

The newly added zero two-channel power amplifier in this upgrade will provide strong and pure driving power for the middle and bass unit in the three-way system.

Overall layout of power amplifier installation. Among them, the white power amplifier is specially responsible for driving the subwoofer. So far, the whole set of three-way active system plus subwoofer realizes that each speaker unit is driven and debugged by an independent power amplifier channel, laying a solid foundation for the ultimate sound quality performance.

The zero 8-inch subwoofer selected in this upgrade is compact in size but contains amazing low-frequency energy and excellent control. It is a key component to improve the low-frequency response of the whole vehicle.
