Cadillac ATS-L audio source core refreshed, equipped with Japanese Biwei eight-channel DSP processor

For senior enthusiasts who have a deep understanding of BEWITH car audio brand, BEWITH’s products often represent the “high-level art” in the field of car audio modification-they usually require precise inverted mold installation and complex system adjustment, so as to completely release their potential to pursue the ultimate clean and delicate sound performance, which puts forward extremely high requirements for the rigor of installation process and the professionalism of debugging technology. However, the “PLUG&PLAY” series, or P&P for short, derived from the same technological pedigree, opens up another path. It completely inherits the core of Biwei’s mature and excellent electroacoustic technology, but precisely focuses its market positioning on mid-range consumer groups who pursue high efficiency, convenience and high cost performance. Its brand name “plug and play” has far-reaching meanings, aiming to break the complex threshold of high-end modification and provide users with an elegant solution that simplifies the installation process, optimizes system matching, and losses sound quality performance.

The Cadillac owner has previously completed an initial upgrade to a sound system. In the audio source signal processing part, the mainstream Magic Cube DSP processor in the market was widely used at that time, because the highly anticipated Biwei brand DSP at that time had not yet been officially launched. Based on the owner’s firm trust in the depth of Biwei Audio’s audio processing technology (the front sound field has selected Biwei AM series two-way speakers), when he learned the latest news that Biwei’s original DSP processor had arrived in the store, he came here without hesitation, determined to make a crucial core upgrade to the “brain” of the system.

 

Here, let’s briefly sort out the complete audio system configuration list presented by this Cadillac after this upgrade. This combination embodies the essence of multiple brands and aims to pursue the ultimate balance and expression:

1. Audio source host: Keep the original main machine to ensure functional integrity.

2. Digital audio processor: BEWITH 8-channel DSP serves as the core hub for system-wide sound quality optimization and sound field adjustment.

3. Front sound field speaker: BEWITH AM series two-way set, driven by active sound division mode to achieve more accurate frequency band control.

4. Subwoofer unit: American DD (Digital Designs) 8-inch original factory preset box subwoofer, providing a solid and flexible low-frequency cornerstone.

5. Main channel power amplifier: Germany’s GLADEN M 90.4 four-channel power amplifier is responsible for the active frequency division system that drives the front sound field with high precision.

6. Ultra-subwoofer power amplifier: Earthquake Q 1800.1 D mono high-power power amplifier, designed to provide abundant energy for driving DD subwoofers.

7. Power system: American Stinger SP 680 high-performance battery provides stable and pure power guarantee for the entire high-power system.

8. All-car wires: Barney (brand) professional audio wires are used to ensure lossless signal transmission and stable and reliable power supply.

 

In this upgrade plan, we adopted a flexible and customer-friendly “equipment discount replacement” model. The owner handed over some of the previously modified equipment to us for professional evaluation and recycling at a discount, and then made up for the corresponding price difference, so as to smoothly upgrade to the new Biwei core processor and other supporting equipment, and achieve a leap-forward improvement in system performance.

The picture shows one of the cores of this system: Biwei AM series two-way speaker unit. Its exquisite craftsmanship and excellent sound quality are the basis for building a high-definition sound field.

In order to ensure the voltage stability under great dynamic conditions, we installed the American Stinger SP 680 high-performance battery for the vehicle. The installation position is reasonably designed, which is stable and easy to maintain.

The soul part of this upgrade-Biwei 8-channel DSP audio processor. It will take over the audio signal of the entire car and perform high-precision time correction, frequency equalization and phase adjustment, which is the key to improving the sound quality level and sense of space.

Thanks to the spacious and well-structured trunk design of Cadillac models, we have hidden and installed all rear-stage power amplifiers, DSP processors and power management equipment on the side wall or bottom of the trunk in a highly integrated and orderly manner. In a specific space, the modification concept of “maximizing sound effects and minimizing space occupation” is perfectly realized.

The American DD 8-inch original refined box subwoofer is cleverly placed at the tail. Its compact size greatly saves space, but the low frequencies it bursts out are deep, clean and elastic, providing solid and stable low-frequency support for the entire sound field without compromise.
