Description
Power Acoustik MA5-2500D 5-Channel Class D Marine Amplifier
Power a compatible boat-audio system with the MA5-2500D 5-channel Class D marine amplifier. Its conformal-coated circuitry and compact housing suit a planned marine installation. Select speakers and wiring around the stated RMS output at your intended load rather than the maximum-power figure.
The MA5-2500D puts four speaker channels plus a dedicated subwoofer channel into a compact Class D platform. Plan the system around its RMS output at the impedance you will actually wire—not the larger maximum-power number in the model’s specifications. Conformal-coated circuitry is a useful marine construction detail, while the narrow chassis gives an installer more flexibility when selecting a protected mounting location.
Key Features
- Class D marine amplifier configured for four speaker channels plus a dedicated subwoofer channel.
- Rated RMS output at 4 ohms: 100x4 +400x1W.
- Rated RMS output at 2 ohms: 150x4 +600x1W.
- Conformal-coated circuitry; RCA and high-level signal-sensing input options.

Why Choose the MA5-2500D?
Choose the channel arrangement that matches the boat’s system rather than adding separate equipment without a wiring plan. Correct load matching, protected cable routing and sensible gain settings are essential to making the amplifier and speakers work together.
Application & Installation
Verify mounting clearance, wiring and amplifier-to-speaker compatibility before installation. Marine equipment still requires suitable placement and protection; do not assume it is submersible.
Frequently Asked Questions
Should I match speakers using maximum or RMS power?
Use the stated RMS output at the intended load as the starting point. Maximum power is a different rating and should not be treated as continuous output.
What channel layout does this model provide?
The MA5-2500D provides four speaker channels plus a dedicated subwoofer channel. Plan speaker quantities and final wired impedance around that layout.
Does conformal coating make it submersible?
Do not treat circuit-board coating as a submersion rating. Install in a protected, ventilated location and follow the manufacturer’s marine wiring instructions.
Can I use a radio without RCA preamp outputs?
High-level signal-sensing inputs provide an alternative to low-level RCA inputs. Confirm the source’s output type and the required wiring before connecting it.
