Power Acoustik MA4-3000D | 3000W Class D 4 Channels Marine Boat Amplifier

The Power Acoustik MA4-3000D is a high-performance 4-channel Class D marine amplifier designed to deliver commanding audio in various environments, including cars, off-road vehicles, motorcycles, and personal watercraft. Part of the Razor Amplifier series, this amplifier is engineered for both durability and versatility.

Its compact 4.75-inch chassis design (1.625″H x 4.75″W x 12.25″L) ensures easy installation in tight spaces. The amplifier features a marinized grade construction with splash-and-spray-resistant conformal-coated circuit boards, guaranteeing reliability and top-shelf performance even in harsh, humid, and vibrating environments.

Equipped with a MOSFET power supply and audiophile-grade IRTM transistors, along with military-grade SMT PCB, the MA4-3000D delivers crisp, efficient, and dynamic sound. It offers flexible channel operation with 2-ohm stereo and 4-ohm bridged full-range capabilities.

Key features include direct short, thermal, and overload protection circuits for safeguarding the amplifier, 200mv-6V low-level RCA inputs, and high-level inputs with signal sense auto turn-on, eliminating the need for a remote wire with factory radios. Variable 12dB high-pass and low-pass crossovers, along with a 10-50Hz variable 12dB subsonic crossover, allow for precise audio customization and subwoofer protection.
