Surge power, pure sound - new AB class car four-channel amplifier

On the journey of speeding wheels, music is an excellent companion to dispel fatigue and ignite passion. However, the original car audio system often struggles to unleash the full charm of music, with blurred details and insufficient dynamics. Today, we bring you an audio weapon that revolutionizes your listening experience: the A125.4 - a Class AB car four-channel amplifier. It is not only a source of energy, but also a restorer of art, aiming to transform your car into a mobile private concert hall.

Power is the cornerstone of an amplifier. This product adopts a wide voltage design (11~15V DC), which can stably adapt to most vehicle electrical systems. Its core advantage lies in its flexible and powerful power output capability:

Standard four-way drive: Under a 4 ohm load, each channel can provide 125W of pure power, which is sufficient to revitalize your speakers for each channel, whether it's vocals, string instruments, or drum beats, all receiving solid and powerful support.

High-energy two-ohm output: When connected to a 2-ohm speaker, the power jumps to 200W x 4. The abundant energy reserve ensures seamless operation even within the maximum dynamic range, rejecting distortion and compression, and perfectly handling loudSpeaker Units with high power requirements.

Professional Bridge Mode: Through bridging, two channels can be combined to deliver a powerful output of 300W x 2 under a 4 ohm load. This mode is specifically designed to drive high-power subwoofers, allowing deep and powerful bass to immerse and thrill you. No need to add additional single-channel amplifiers, making the system construction simpler and more efficient.

Whether it's upgrading four-Door Speakers, constructing an active crossover system, or driving a composite system with front and rear sound fields plus subwoofer, this four-channel amplifier can provide a precise and powerful solution.

We are well aware that a truly "good sound" goes far beyond mere power figures. It's about the details, about purity, and about utmost fidelity to the original sound. This power amplifier utilizes the classic Class AB amplification circuit, achieving a perfect balance between efficiency and sound quality, while avoiding the "digital taste" that may exist in Class D power amplifiers.

Broad frequency response (10Hz - 55KHz): far exceeding the human auditory limit (20Hz-20KHz), meaning it can fully capture the extremely low-frequency overtones and extremely high-frequency airy feel and details in the recording, making the musical image more complete and immersive.

An extremely high signal-to-noise ratio (100dB): This means that the background is almost "pitch black". During pauses in the music, you can't hear any irritating "hissing" background noise; when the music starts, every subtle detail is clearly distinguishable, and the sound quality is as pure as crystal.

Excellent channel separation (60dB): ensures that signals between the four channels do not interfere with each other, creating an extremely precise and wide sound field positioning. You can clearly "see" the singer in the center, with instruments neatly arranged on both sides, providing an immersive stage listening experience.

Extremely low distortion rate (<0.05%): Regardless of the volume level, the signal is transmitted with almost no loss or distortion. The emotions in the music are presented authentically, with warm vocals and sharp guitar solos sounding incredibly real and natural, never getting old even after repeated listening.

To accommodate various audio source head units, we offer an adjustable input sensitivity ranging from 250mV to 2V. Whether it's an original car head unit or a high-end modified one, it can be easily matched to achieve the optimal input level. With an input impedance of up to 22K ohms, signal transmission loss is effectively reduced, ensuring the integrity of information from the audio source to the power amplifier.
