    Big Power in a Compact Design

    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.

    MA400.4 Built for Harsh Conditions

    Built for Harsh Conditions

    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.

    MA400.4 Efficient Power you can Rely On

    Efficient Power you can Rely On

    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.

    MA400.4 Protection and Piece of Mind

    Protection and Piece of Mind

    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.
