The DOWN4SOUND M3-1004 Marine & Off-Road Amplifier is a compact 4-channel Class D amplifier delivering 700 watts RMS of clean, efficient power for boats, jet skis, side-by-sides, UTVs, motorcycles, mud trucks, and off-road builds.
Engineered for demanding marine and outdoor environments, this amplifier features a sealed aluminum chassis, conformal-coated internal PCB, and corrosion-resistant terminals designed to withstand moisture, salt air, mud, vibration, and real-world exposure.
With proper installation, the M3-1004 is built to handle extreme marine conditions, including high-moisture and water-exposed applications. Whether mounted in a wake boat hull, jet ski compartment, motorcycle saddlebag, side-by-side dash, mud truck cab, or custom off-road build, it delivers reliable performance with confidence.
The Blue Glowtek edition adds a bold visual signature without compromising durability or output.
Blue Glow Finish
The housing features Glowtek Blue technology, a glow-in-the-dark finish that charges from natural sunlight or artificial light sources.
Charges from any natural or artificial light source
Emits a visible blue glow in low-light and dark environments
Glow effect naturally dissipates over time as stored light energy is released
Rechargeable, exposure to light renews the glow effect repeatedly
No wiring, batteries, or external power required for illumination
The glow intensity gradually fades as energy dissipates and can be restored anytime by re-exposing the surface to light. The finish delivers a clean, aggressive aesthetic for night runs, dock presence, and show builds without affecting amplifier performance or reliability.
Power Output
4 × 100W RMS @ 4 ohms
4 × 160W RMS @ 2 ohms
2 × 330W RMS @ 4 ohms bridged
700W RMS total output
Full-range Class D design ensures high efficiency and reduced heat, ideal for marine and powersports electrical systems.
