MRD1500.1

Take your boat's bass to the next level with the Rockville MRD1500.1 — a USA-engineered Class D monoblock that delivers a dyno-tested 1500W RMS @ 1Ω with marine-grade toughness. Compact, efficient, and built to dominate the waves without draining your battery or overheating in harsh conditions.

Marine-Ready Style & Protection:

• Stunning White Design: The amp, matching white metal bass remote, and white remote cable create a sleek, cohesive look that stands out on any boat.
• Silicone Terminal Covers: Included white silicone covers with stretchy holes squeeze tightly around all cables — power, ground, remote wire, RCAs, and even the bass remote wire — ensuring extra water-tight seals for every single terminal. Removable caps included for unused RCA terminals.
• Marine-Grade Fuse Holder: A matching white silicone cover houses a true marine-grade 150A fuse designed to block water intrusion and ensure reliable power delivery.
• All-Stainless Steel & Aluminum Construction: Every component, including hardware, is made from corrosion-resistant stainless steel or aluminum alloy for unmatched durability in saltwater environments.

More Watts Per Dollar!
We deliver more true RMS watts per dollar spent than our competitors — especially considering this amp was properly engineered in the USA.

Compact Design
The MRD series is a compact Class D amp that won't take up valuable space on your boat.

Metal Bass Remote with Clipping Indicator
Includes a high-quality metal bass remote with a clipping indicator so you can easily maximize bass before distortion in real time.

Precision Controls
Bass Boost (0dB–12dB at 45Hz), Low Pass Filter (45Hz–200Hz), and Subsonic Filter (10Hz–50Hz) give you full control over your system. Input level (265mVrms–6.5Vrms) adjusts to match various source units for clear sound.

Tiffany-Style RCA Terminals
Premium Tiffany-style RCA terminals for the most secure and reliable connections.

Engineered in the USA for Superior Performance
Top-tier efficiency reduces battery strain compared to competitors. The precisely engineered 45Hz Bass Boost outperforms rival 80Hz boosts, and the amp handles heat exceptionally well — passing a 30-minute full-power test at 100Hz without thermal protection triggering.

True Class D Design
This is a true Class D design — not a half-bridge design. Half-bridge designs are cheap to produce, but their sound quality, longevity, and safety are questionable.

Proudly engineered in the USA — dyno-tested for real-world reliability.
