MA5-2500D | 2500W Class D 5 Channel Marine Amplifier

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

The MA5-2500D is designed specifically for watercraft, UTVs, ATVs, motorcycles, and other outdoor audio applications where durability is non-negotiable. Its splash-resistant internal components are conformal coated to protect against corrosion, moisture, and salt spray.

Unlike generic “water-resistant” amps, this one is built from the circuit board up to withstand real-world marine conditions.

Real Performance Across 5 Channels

Powering a full soundstage? Running dedicated channels to a subwoofer and four full-range speakers? This amp does it with headroom to spare.

Output Ratings:

• 4 × 100W + 1 × 400W @ 4 Ohm RMS
• 4 × 150W + 1 × 600W @ 2 Ohm RMS
• 2 × 300W (bridged) + 600W sub channel @ 2 Ohm
• 2,500W peak power (max)

These outputs provide the flexibility to run a front/rear plus subwoofer setup or bridge channels for increased power where it matters.

Compact Footprint, Serious Build

Its dimensions — approx. 12.25" L x 4.75" W x 1.625" H — allow placement in tight consoles, under seats, or inside weather-protected marine compartments. It’s a match for installations where space is limited, but output requirements are not.

Construction highlights include:

• Class D topology for low heat and efficient power delivery
• MOSFET power supply and IRTM audiophile-grade transistors
• SMT PCB assembly – increases vibration resistance and longevity
• Sealed, marine-safe terminals for long-term connection integrity

Precision Tuning for Demanding Systems

Audio control matters — especially in marine and off-road setups where cabin acoustics are unpredictable. The MA5-2500D gives you:

• Variable 12 dB high-pass and low-pass crossovers (35–250 Hz)
• Variable subsonic crossover (10–50 Hz) to remove inaudible low-end
• Dash-mount remote gain control for on-the-fly subwoofer adjustments
• LED power/protection indicators for system diagnostics

Seamless Integration with Factory or Aftermarket Head Units

For those using factory radios without dedicated remote turn-on leads, the signal-sensing auto turn-on via high-level speaker input is a game-changer. It powers on when it detects audio — no extra wiring needed.

Input Options:

• Low-level RCA input (200 mV – 6 V)
• High-level speaker input with signal sense
• Supports 8 AWG power and speaker wire

This gives you installation flexibility whether you're upgrading a marine factory system or adding amps to a custom boat or UTV setup.
