For years, I struggled with underwhelming bass in my home theater system. The lack of deep, resonant low frequencies significantly impacted my movie-watching and music-listening experience. While I considered various solutions, a dedicated subwoofer amplifier seemed like the most promising option to truly enhance the audio quality. I knew that without a powerful solution, my home entertainment would continue to lack the punch and depth it deserved.
The primary purpose of a subwoofer amplifier is to boost the low-frequency sound output of passive subwoofers. This is crucial for those who want a truly immersive audio experience, particularly for movies and music genres with heavy bass lines. The ideal customer for a subwoofer amplifier is someone with a passive subwoofer seeking to improve its performance, especially those wanting to avoid the added expense and possible quality compromises of an active subwoofer. Those who already own a powerful active subwoofer or who prioritize high-fidelity audio reproduction in the upper frequencies might not benefit greatly from a dedicated subwoofer amplifier and should consider other audio enhancements instead. Before purchasing, consider factors such as the power output (watts), the impedance of your subwoofer, the presence of features like a low-pass filter and crossover adjustments, and the overall build quality.

Introducing the Fosi Audio M04 Subwoofer Amplifier
The Fosi Audio M04 Subwoofer Amplifier is a compact, mono-channel Class D amplifier designed to power passive subwoofers. It promises powerful bass reproduction with a clean, clear sound. The package includes the amplifier unit itself, a 19V/4.74A power supply, and a user manual. Compared to market leaders, the M04 boasts a significantly more affordable price point while maintaining impressive specifications. Previous versions of Fosi Audio amplifiers also lacked some of the features, such as the switchable subwoofer/full-range mode, now found in the M04. This amplifier is ideal for those looking for a budget-friendly solution to enhance their subwoofer’s performance. However, those requiring extremely high power output or extensive customization options may want to consider more advanced (and typically pricier) models.
- Pros: Compact design, powerful output (100W max), included power supply, affordable price, versatile subwoofer/full-range mode, clean audio reproduction.
- Cons: Limited features compared to high-end models, the volume control doubles as the on/off switch, potentially some background noise at very low volumes.

Unveiling the Features and Benefits of the Fosi Audio M04
Power and Performance
The Fosi Audio M04‘s 100-watt maximum power output is surprisingly potent for such a small device. It effortlessly drives my 8-inch subwoofer, delivering deep, rich bass without any noticeable distortion even at higher volumes. The Class D amplification technology is highly efficient, resulting in minimal heat generation, even during prolonged use. This efficiency translates into lower energy consumption, a welcome bonus in my books.
Compact Design and Ease of Use
The M04’s small footprint is a major advantage. It easily fits into tight spaces, making it ideal for setups where space is at a premium. The straightforward design and intuitive controls make setup a breeze. While some users mentioned the combined volume and power switch as a minor drawback, I’ve found it perfectly usable after a short learning curve. Its compact size and ease of installation were significant factors in my decision to use it in my subwoofer rebuild project.
Subwoofer/Full-Range Mode Selectability
The switchable modes are a feature I genuinely appreciate. The ability to switch between subwoofer mode (ideal for dedicated low-frequency enhancement) and full-range mode (useful for driving smaller speakers or adding bass to a main system) offers incredible flexibility. This makes the Fosi Audio M04 exceptionally versatile, suitable for multiple audio applications.
Build Quality and Reliability
Despite its compact size and affordable price, the Fosi Audio M04 feels incredibly robust. The metal casing adds a premium feel and protects the internal components from damage.

It has proven to be a reliable and durable component in my home theater system.
Sound Quality and Clarity
The sound quality produced by the M04 is excellent. The bass is deep, accurate, and well-defined, free from any unpleasant muddiness or distortion. This is a testament to the quality of its components (Texas Instruments TPA3116 chip and NE5532 op-amp) and its class D amplification capabilities. The low-pass filter effectively manages the frequency response, ensuring that the subwoofer only receives the frequencies it’s designed to handle, enhancing the overall sound clarity. The overall audio reproduction remains clean and clear, whether I’m watching action movies or listening to my favorite music.
User Experiences – Positive Feedback Across the Board
My experience with the Fosi Audio M04 is echoed by countless positive user reviews online. Many users praise its powerful output, compact design, and surprising sound quality for its price.
