【KICKER CXA800.1 | Monoblock Power Amplifier for Subwoofers】

Even after adding a subwoofer, you may want a bit more overall bass quantity. Or maybe the low frequencies turn blurry when you raise the volume. The KICKER CXA800.1 monoblock power amplifier is designed to address exactly those kinds of concerns.

With a 1ch dedicated design, it provides enough output to drive your subwoofer properly. It delivers 800W RMS at 1Ω, 600W RMS at 2Ω, and 300W RMS at 4Ω. Not only does it bring out the punch of the bass, but it also adds thickness and an air-like sense of presence that are difficult to reproduce with front speakers alone—supporting the entire music spectrum from the bottom.

It also supports bass adjustment with a variable low-pass filter, a subsonic filter, and KickEQ. The key point is that you can fine-tune the low end while keeping the subwoofer from standing out too much, maintaining a seamless connection with the front speakers. With the separately sold remote base controller, you can adjust the bass level from the driver’s seat, making it easier to handle depending on the music you usually listen to and your mood that day.

While it’s easy to fit into a compact size, what you need can vary depending on power wiring and fuse capacity, the subwoofer’s impedance, and the installation location. Even with the same CXA800.1, the final result changes depending on which subwoofer you pair it with and how you install and adjust it.

If it were me, I wouldn’t decide based on the amplifier’s output alone. I’d check your vehicle’s factory audio and your current system as a whole, then consider the best combination. This is a power amplifier I’d like you to consult with—whether you want more bass, or you want “the quantity, but not a sound where only the bass stands out.”
