Built for the Water, Ready for the Ride

Engineered for life on the water, the MA1400.5 features a conformal-coated circuit board that shields against moisture, salt, and spray. This ensures long-term reliability in harsh marine environments. Stainless steel hardware adds an extra layer of corrosion resistance, making it tough enough for any ride.

Audio Power, Anywhere you Anchor

With four full-range channels delivering up to 100W RMS each at 2Ω and a dedicated subwoofer channel pushing up to 800W RMS at 1Ω, the MA1400.5 brings smooth mids, crisp highs, and thunderous lows to every corner of your vessel. No matter the conditions, your sound stays loud and clear.

Despite its high output, the MA1400.5’s compact chassis fits easily into tight compartments or under seats, with a durable design that holds up to vibration and weather. Every unit comes with a Dyno Power Rating Certificate, so you know you’re getting real, tested power.
