Description
Kicker 46CXA400.1 CX-Series 400Watt RMS Monoblock Class D Amplifier
The Kicker CX-Series amplifiers reach impressive power levels thanks to an optimized circuit layout and high-grade internal components. Additionally, highly efficient heat sinks keep the amplifier cool while maintaining a clean, modern look. For added convenience, mono models support an optional remote level control for easy bass adjustment from the dash.
Power Pack Performance
First of all, the CXA400.1 is now one-ohm stable, which provides more wiring flexibility and higher output potential. Using a compact Class-D design, this amplifier delivers strong bass while remaining energy efficient. As a result, you get powerful performance without excessive heat buildup.
Furthermore, this amplifier delivers up to 400 watts RMS into a single bass channel, making it ideal for compact subwoofer systems.
Advanced Bass Control & Tuning
In addition, the CXA400.1 includes built-in tools that allow precise system tuning. A variable KickEQ™ bass boost provides up to 6dB at 40Hz, while the 12dB low-pass crossover and 24dB subsonic filter help protect your subwoofer and improve sound quality.
Because of these controls, dialing in clean, powerful bass is both simple and precise.
Flexible Integration with FIT+™ Technology
Moreover, CX.1 amplifiers accept up to 40 volts of speaker-level input. Therefore, a line-out converter is often unnecessary. At the same time, FIT+™ (Fail-safe Integration Technology-PLUS) ensures excellent noise rejection, even when used with premium factory audio systems.
This flexibility allows the amplifier to work reliably with almost any radio.
Expandable System Design
Additionally, the CXA400.1 features full-range RCA pass-through outputs, making future system expansion easy. You can add another bass amp or a full-range amplifier without re-routing signals.
To complete the installation, the amplifier includes both horizontal and vertical mounting hardware, giving you more layout options and a custom look.
Remote Bass Control Ready
For even more control, this mono amplifier is compatible with the CXARC Remote Bass Controller (sold separately). As a result, bass output can be adjusted instantly from the driver’s seat, depending on your music or driving preferences.
