The Ampere Audio AA-200.4 was engineered to solve that problem by delivering powerful full-range performance in a compact, feature-rich package. Why Speaker Power Matters Factory head units and underpowered amplifiers often leave speakers operating far below their potential. The result is reduced output, limited dynamics, and distortion when volume levels increase. Upgrading your speakers without providing adequate power often leads to disappointing results and wasted performance. The AA-200.4 delivers the clean power needed to unlock the full potential of your audio system. Producing up to 200 watts RMS per channel at 4 ohms and 350 watts RMS per channel at 2 ohms, this amplifier provides the headroom needed for improved clarity, increased output, and greater overall control. Whether you're powering component speakers, pro audio mids and highs, or a combination of speakers and subwoofers, the AA-200.4 delivers the performance needed to bring your music to life. Built for Versatility The AA-200.4 was designed for enthusiasts who want flexibility. Its full-range Class D design allows it to be used in a variety of system configurations, from traditional four-speaker setups to active systems and even bridged applications for subwoofers. Advanced crossover controls with selectable x1 and x10 multipliers provide an extremely wide tuning range, making it easy to integrate with everything from tweeters and midrange speakers to pro audio drivers and subwoofers. A built-in Perfect Band-Pass Filter gives you even more control over your system, allowing precise tuning for maximum performance. Key features include: 200 Watts RMS x 4 @ 4 Ohms 350 Watts RMS x 4 @ 2 Ohms 750 Watts RMS x 2 Bridged @ 4 Ohms Full Range Class D Technology Perfect Band-Pass Filtering Variable High Pass and Low Pass Crossovers x1 / x10 Crossover Multipliers Clipping Indicators High-Efficiency Design 4-Way Protection Circuitry Precision Control for Every Build Every system is different, and the AA-200.4 provides the tuning flexibility needed to maximize performance. Adjustable high-pass and low-pass filters allow you to dial in crossover points with precision, while the crossover multiplier expands adjustment ranges for more advanced system configurations. Whether you're building a loud daily driver, powering a full active front stage, or creating a dedicated mids and highs system, the AA-200.4 gives you the control needed to optimize every speaker in your vehicle. Integrated clipping indicators also help you monitor system performance and avoid distortion when pushing your system hard. Built to Play Loud and Stay Reliable Power means nothing without reliability. That's why the AA-200.4 incorporates a comprehensive 4-Way Protection Circuit that safeguards the amplifier from thermal overload, voltage fluctuations, speaker shorts, and DC offset conditions. Combined with its highly efficient Class D design, the amplifier runs cooler and more efficiently than traditional amplifier designs.
