Marine 4-Channel Amplifier Kit

The Sound PLMRMB4CW is a compact marine-grade amplifier kit designed for boat owners who want a complete audio upgrade with Bluetooth streaming. It delivers four channels of Class AB power and includes the wiring and mounting hardware needed for installation on a vessel.

Thermals Noise Power

Class AB topology provides reliable output with 200W RMS and 400W peak across four channels while the unit can be bridged for 800W into two channels. CEA-2006 compliance confirms the power ratings are measured to a consistent standard and the 12V DC input suits typical marine electrical systems.

Included Wiring Hardware

The bundled power wiring kit and mounting hardware remove the need to source separate cables and brackets for a standard install. Built-in crossover and bass boost controls let you shape the sound without an external processor while RCA and speaker-level inputs offer flexible source connection.

Questions about this item

How do I wire the PLMRMB4CW to a 12V DC source and which input should I use for a factory head unit?

Run fused power to the 12V DC terminal, secure a clean chassis ground, then connect the factory speaker wires to the speaker-level inputs — no RCA adaptor needed.

What regular upkeep does the Class AB marine amplifier require after installation?

Inspect the power and speaker terminals for corrosion each season, tighten any loose set-screws, and verify the fuse holder remains sealed against moisture.

At what output level does the built-in protection engage during extended high-volume playback?

The amplifier delivers 200W RMS across four channels; sustained demand beyond that rating triggers the thermal and current protection circuits.
