Power Acoustik MA5-2500D – 2,500W 5-Channel Marine-Class D Amplifier (Razor Series)

The Power Acoustik MA5-2500D is a high-efficiency 5-channel Class D amplifier engineered for marine and off-road environments. As part of the Razor Series, this model integrates Class D technology with marine-grade protection features, allowing it to power your full-range system and subwoofer with clarity, durability, and reliable output even in moisture-rich or vibration-heavy conditions.

With a combined RMS rating of 1,200 watts and a peak output of 2,500 watts, the MA5-2500D delivers serious performance across 5 discrete channels. It supports both OEM and aftermarket integrations, features automated signal sensing, and includes a compact chassis that fits in tight installs without sacrificing power.

Built for Marine and Powersport Use, its splash-resistant internal components are conformal coated to protect against corrosion, moisture, and salt spray. Construction highlights include Class D topology for low heat and efficient power delivery, a MOSFET power supply with audiophile-grade IRTM transistors, SMT PCB assembly for increased vibration resistance and longevity, and sealed, marine-safe terminals for long-term connection integrity.

Precision tuning for demanding systems is provided through variable 12 dB high-pass and low-pass crossovers (35–250 Hz), a variable subsonic crossover (10–50 Hz) to remove inaudible low-end, and a dash-mount remote gain control for on-the-fly subwoofer adjustments.
