Marine-Grade Class D Amplifier with Enhanced Bass

Built to withstand the harshest marine environments, this amplifier features REAL MARINE™ construction, including anti-corrosive speaker, power, and RCA terminals, stainless-steel screws, conformal-coated circuit boards, and ABYC/NMMA-compliant power connections for long-lasting durability in saltwater, UV, and humid conditions. Its high-efficiency Class D design delivers clean power to multiple channels without excessive heat or space consumption, while the KickEQ™ Bass Boost offers a variable 0–6 dB enhancement at 40 Hz for deeper, punchier low-end performance.

Precision DSP Marine Amplifier with Advanced Controls

This amplifier features a variable 24 dB crossover for precise high-pass, low-pass, or band-pass tuning, ensuring each speaker performs optimally. The DSP-controlled preamp enhances signal clarity and minimizes distortion for high-fidelity audio, while the gain control with “Gain Match” LED indicator simplifies setup by showing when the input signal is properly matched.

  • All my speakers sounds so much better now! Love the power coming from this amp. Way better than the old amp I have before this one.

  • Nice amp. Made my speakers sound better after setting it up. I haven't tried it in open waters though so I can't say yet how good really it can be with all the noises coming around. I also hope it won't break that easily just like the amp I got before this.

  • soundwise, one of the best of I've ever heard. they're not cheap but they're not that expensive too. the price just sits right there. loud, clear, and powerful. has a sturdy build. hope it would reach years before I have to buy a new one
