Sound quality and energy consumption are fully considered

2025,07,26

Traditional Car Audio faces the dual pain points of compromised sound quality and high energy consumption: large screen navigation has poor sound quality, and disassembly and assembly can easily damage the original car system; under the anxiety of electric vehicle range, traditional audio has high power consumption and takes up space; rear-mounted subwoofer has messy wiring and muddy sound field. Does your car's navigation sound harsh, high-frequency distortion after modification? Or does the installation of Electric Vehicle Dsp Subwoofer cause a surge in power consumption? Our solution integrates three major technological innovations:

Solution and effectiveness

DSP sound quality revolution: Luchang 820 car machine has built-in 434-band equalization adjustment DSP chip, adaptive tuning for car models, solves the pain point of "digital sound" of navigation machine, supports optical fiber/RCA output, and subsequent installation of power amplifier for lossless upgrade19;

Efficient energy-saving architecture: Adopting STMicroelectronics HFDA90D digital power amplifier, 2MHz high-frequency technology to achieve four-channel 108W output, 70% smaller volume, 40% lower power consumption, and adapting to electric vehicle 18V high-voltage system58;

Spatial acoustic optimization: Drawing on Panasonic EV's exclusive audio design, using the windshield as the sound field reflection surface, only 2.5-inch Electric Vehicle Faucet Speaker (water-saving cavity design) is needed to achieve full cabin surround, and energy consumption is reduced by 65%6 compared with traditional systems.

Actual test results: The low-frequency diving depth of Luchang head unit reaches 20Hz, and the mid-frequency density is comparable to that of McIntosh CD player; when the energy-saving amplifier drives the Electric Vehicle DSP Subwoofer, the transient distortion is less than 0.0008%, and the endurance is stress-free18. Motorcycle Audio is upgraded synchronously, and the waterproof cavity of Electric Vehicle Handlebar Speakers is adapted to the motorcycle handlebars, with a peak power of 90W and no fear of wind noise10.

Product features and tips

1. Special car tuning database: Luchang DSP preloads 200+ car model sound parameters, and the mobile phone matches the original Car Speakers with one click9;

2. Frequency division energy saving technique: Bass is independent 250W amplifier channel, mid-high frequency is driven by 45W module, and power consumption is dynamically allocated8;

3. Streamlined wiring harness: Digital direct connection architecture saves DAC module and reduces 80% wiring5.

Tips: For electric vehicles, it is recommended to choose speakers with a sensitivity of ＞99dB (such as Electro-Voice SX100), which can reduce power consumption by 30% at the same sound pressure210; when modifying Motorcycle Audio, the handlebar speakers should be tilted towards the ears to avoid sound wave scattering.
