Rockville DBM50 4000W Peak / 980W RMS 5-Channel Marine Amplifier | IPX6 Waterproof, Adjustable Crossover, PA Mic

Meet the Rockville DBM50, a rugged marine amplifier designed to bring clear, dynamic sound to boats of all sizes. Delivering 4000W peak and 980W RMS across five channels, it powers four full-range outputs and a dedicated sub channel, creating a balanced audio foundation for deck, cockpit, and cabin listening experiences.

Whether you're enjoying a sunny day on a wakeboard run or hosting a sunset party, the DBM50 offers flexibility you can feel. The 4 full-range channels (120W x 4 at 2 ohms) drive midrange clarity and vocal presence, while the mono sub channel (500W at 2 ohms) adds controlled bass that remains musical rather than overwhelming in open-air settings. Tuning is easy with a fully adjustable 12dB/octave crossover that covers low pass, high pass, bandpass, and subsonic filters, enabling precise shaping for subwoofers, full-range speakers, and midrange cabinets.

Onboard control and easy connectivity

Includes a PA microphone for onboard announcements and a remote subwoofer control for quick bass tweaks from the helm or seating area. The DBM50 is designed to work with marine speakers from popular brands, making it simpler to assemble a system that suits your boat’s layout.

• Fully adjustable crossover for subwoofers and full-range components
• Remote bass control for convenient adjustments while cruising
• PA microphone included for crew or guest communications
• Class AB power on channels 1–4 and Class D power on channel 5 for efficient operation

Durability built for salt and spray

Rockville built the DBM50 to withstand the realities of marine life. Its IPX6 waterproof rating guards against powerful sprays, while a rustproof aluminum heat sink and stainless steel hardware resist corrosion. A conformal-coated PCB adds another layer of protection against humidity and salt fog, helping your system stay reliable in changing conditions.

• IPX6 rating protects against splashes and washdowns
• Rustproof aluminum heat sink supports steady operation in heat
• Stainless steel hardware resists corrosion from saltwater
• Conformal-coated PCB guards sensitive circuits

Practical and scalable, the DBM50 offers a clear path to a boat-ready audio setup. It can power deck speakers for entertaining guests, or deliver subtle background sound during long crossings while conserving battery life thanks to efficient power delivery.
