The MA400.4 delivers 100 watts RMS per channel at 2Ω, pushing crisp, distortion-free sound through every speaker in your setup. Its compact footprint makes it easy to install without sacrificing performance. Each amp includes a Dyno Power Rating Certificate, confirming that you’re getting real, verified power.
Marine-specific upgrades make the MA400.4 a durable choice for life on the water. A conformal-coated circuit board protects against salt and moisture, while stainless steel hardware resists corrosion over time. It’s designed to stand up to the elements without compromising audio quality.
With Class D circuitry, the MA400.4 runs cool and efficient even when pushed at high volume. Its surface mount component design keeps connections stable and secure, maintaining consistent output even in high-vibration environments.
Fine-tune your audio with variable gain and crossover settings, all hidden beneath a clean, low-profile panel. An LED indicator keeps you informed of power or protection status, monitoring for voltage issues or overheating so your system stays safe and sounding great.
