Marine Monoblock Amplifier

The Skar Audio RP-1500.1DM is a Class D monoblock subwoofer amplifier built for marine environments. It delivers 1500 watts RMS at 1 ohm with a peak rating of 2300 watts. The circuit board features a waterproof coating and the mechanical case uses rust-proof paint with stainless steel hardware.

Protection And Tuning Features

Four-way protection circuitry covers thermal, voltage, speaker and DC faults. On-board controls include a bass EQ switch offering 0, 6 or 12 dB boost at 45 Hz, adjustable gain, low-pass filter and subsonic filter. A remote subwoofer level control is included and 4-gauge power and ground terminals support maximum current flow.

Boats Needing Single High-Power Sub Channel

This amplifier suits installations that require one powerful subwoofer channel in wet or salty conditions. It is not for systems needing multi-channel amplification or full-range speaker outputs. Buyers who want integrated DSP, wireless control or multiple impedance options beyond 1 ohm stability should look at something else.

Questions about this item

What maintenance does the waterproof coating on the circuit board require over time?

The circuit board has a waterproof coating and the mechanical case uses rust proof painting with stainless steel hardware, so no routine maintenance of those protections is needed.

What limits continuous output when the amplifier runs at 1 ohm for long periods?

The 4 way protection circuitry monitors thermal, voltage, speaker and DC conditions and will limit output if any threshold is exceeded.

How much heat does the heatsink dissipate when the amp delivers 1500 watts RMS all day?

The highly efficient heatsink design is built for maximum reliability and performance at the rated 1500 watts RMS into 1 ohm.
