In the Camry, hear every detail of the music: a systematic sound insulation and two-way upgrade solution

Far from simply parts replacement, car audio modification is a technical service industry that combines acoustics, electronic engineering and precision manufacturing. Its real value lies not only in the moment the installation is completed, but also in whether it can provide car owners with products that can stand the test of time and continue to bring pleasure through rigorous craftsmanship and scientific combinationLong-lasting auditory value。 That’s why we put a lot of effort into repeated testing when researching and matching each standardized upgrade package for our trusted customers. From the individual performance evaluation of each equipment unit, to the matching demonstration of their collaborative work in the whole system, to the final overall listening verification, every link has been carefully considered and strictly controlled. Only in this way can we deliver these solutions with painstaking efforts and professional knowledge to those car owners who always trust us with full confidence.

The owner of Toyota Camry this time came through the enthusiastic recommendation of one of our satisfied old customers. He chose the carefully tuned two-way upgrade package below, and additionally optioned the entire vehicle sound insulation and noise reduction project. This is not only a sound upgrade, but also a quiet, pure and focused environment in your car“Mobile Concert Hall”Lay the crucial physical foundation.

 

In-depth analysis of package system architecture
Different from previous two-way basic packages, a significant evolution of this system is the addition ofRear sound field horn system。 The driver and management core of the whole system is a powerful Aiwei eight-channel DSP power amplifier. Through its powerful processing capabilities, we achieve“Active crossover drive of front sound field” and “passive crossover supplement of rear sound field”Advanced gameplay. The two speaker units (treble and mid-bass) in the front sound field are driven by independent channels of DSP power amplifier to achieve the most accurate control and adjustment; The rear sound field serves as a supplement to the atmosphere, expanding the surrounding feeling of the sound field in an efficient way. After professional debugging, this architecture can ensure the ultimate analysis and positioning of the “emperor’s position” in the front row.Rear passengers can also enjoy a balanced and full listening experience, truly taking care of the listening experience of all vehicle occupants. For the subwoofer part, we chose the Danish B 2 brand subwoofer with its own high-efficiency single-channel power amplifier. The integrated design not only simplifies the installation, but also ensures the strength and speed of low frequency. This complete set of solutions perfectly fits our store’s consistent adherence“Cut the complexity and simplify it, and the effect is supreme”On the premise of ensuring that the system is simple, stable and easy to maintain, we are committed to bringing customers a surprise-level sound experience that far exceeds expectations.

 

 

The following is a panoramic view of the construction process and core process details of this upgrade

The first stage: entire vehicle sound insulation and noise reduction-building a quiet acoustic canvas

First, the sound insulation and vibration stopping construction in the chassis area is carried out. High-density vibration-stopping plates are mounted on a large area to effectively suppress the resonance of sheet metal parts during driving and reduce low-frequency noise from the source.

The trunk is the main incoming area of road noise and exhaust resonance. Strict anti-vibration treatment in this area can significantly improve the quietness of the whole vehicle.

In view of tire rolling noise, the front wheel fender and the inner sheet metal are sound insulated.

A special sound-absorbing material is pasted on the inside of the tire lining plate to directly absorb the noise caused by the friction between the tire and the ground.

Above the vibration-stopping layer, environmentally friendly sound-absorbing cotton is fully laid to further absorb medium and high-frequency noise, completing the triple protection system of “vibration-stopping + sound insulation + sound absorption”.

 

 

 

The second stage: core modification of the sound system-see the real chapter in the details

In order to ensure that the performance of every piece of equipment is thoroughly stimulated, we always adhere to a principle: abandon the thinner and ordinary speaker cables of the original car, and completely replace them with professional-grade speaker cables of higher quality and lower loss, from the transmission channel. Ensure the purity and integrity of the signal.

Every installation link is about the final sound quality. We customize high precision horn gaskets for specific vehicle models, ensuring a solid and sealed installation. What the industry often says is “three-point equipment, seven-point modification”, which is most intuitively reflected in every construction detail of our work.

Eliminating air leakage is the lifeline to ensure the purity of medium and low frequencies.We will never allow any gap between the horn and the mounting surface. Through tight sealing treatment, the “puffing” noise and distortion caused by airflow leakage are completely eliminated. This makes the mid-bass sound cleaner, firm, full and bouncy. We never blindly follow the trend or imitate other people’s rough craftsmanship. As early asAnnual Report 2013, we took the lead in establishing and disclosing a complete set of“Speaker Installation Process Standard”(The official website has detailed records). Old friends who have been following us for more than six years should know that we are always committed toBecome the setter of industry standards and the pioneer of process innovationRather than simply followers.

The installation of the magic cube set speaker in the rear sound field also follows high standards to ensure its clarity and stability as a supplement to the sound field.

 

The installation of the tweeter unit is key to shaping a wide loud sound field. Through the adjustable angle installation method, we flexibly use the principle of sound directivity to allow high-frequency energy to be accurately projected. This ingenious application of technology can create aUnusually open, far-reaching soundstage effects out of the windshield, completely breaking the physical limitations of space.
