My long-term experience with the Kicker 46CXA8001 CXA8001-800-Watt Mono Class D Subwoofer Amp has truly cemented its place as a powerhouse in a remarkably compact form. Having put it through its paces across various music genres and demanding scenarios, I can confidently break down what makes this amplifier such a standout performer.
Powerful Class D Performance (800 Watts RMS)
The heart of the Kicker CXA8001 lies in its ability to consistently deliver 800 watts RMS of clean power. From the moment I first wired it up, the difference was astounding. My subwoofers, which previously sounded good, suddenly came alive with a new level of authority and clarity. This isn’t just about loudness; it’s about the quality of the sound. The bass hits are tighter, more defined, and have a tangible impact that was simply missing before. Even at higher volumes, the sound remains clean, with minimal audible distortion, which speaks volumes about the amp’s robust design.
This feature is paramount because many subwoofers require significant, stable power to perform optimally. Underpowering a subwoofer can lead to muddy, distorted bass, and can even damage the voice coils over time due to clipping. The Kicker CXA8001’s substantial RMS output ensures that your subwoofers receive all the power they need to reproduce deep, accurate bass frequencies without straining. This provides a truly immersive listening experience, allowing you to feel the music as much as you hear it, solving the core problem of weak or undefined low-end audio. The Class D architecture also means this impressive power is delivered with remarkable efficiency, translating into less heat and lower current draw compared to older amplifier designs.
One-Ohm Stability for Ultimate Flexibility
One of the most impressive aspects of the Kicker 46CXA8001 is its ability to operate stably at impedances down to one Ohm. This seemingly technical detail has enormous practical benefits. It allows for an incredible range of subwoofer wiring configurations. Whether you have a single dual voice coil (DVC) subwoofer or multiple single voice coil (SVC) subs, you can often wire them in parallel to achieve a 1-Ohm load, thereby extracting the maximum power from the amplifier.
In my own setup, this flexibility meant I wasn’t limited by the impedance of my chosen subwoofers. I could experiment with different wiring schemes to optimize the power delivery, ensuring my subs were getting the exact amount of juice they needed. This feature is crucial for anyone building a custom system or planning to upgrade their subwoofers in the future, as it ensures the amplifier can adapt to various speaker configurations without needing to be replaced.
