SoundStream Rubicon MR4.1400D Nano Marine 1400 Watt 4-Channel Class D Amplifier

Designed for boats and watercraft, this marine-grade 4-channel, high-efficiency class D full-range amplifier delivers reliable audio performance in wet environments. It uses a hybrid aluminum alloy heatsink to maximize heat dissipation and improve safety for worry-free marine operation. The unit is driven by a metal-oxide-semiconductor field-effect transistor power supply for enhanced durability, coupled with audiophile-grade infrared thermal mapper transistors for thermal management. Built on military-grade printed circuit board surface mount technology, the amplifier maintains dynamic, long-lasting system performance. Flexible wiring and tuning options include dual system impedance: 2 Ohms in stereo mode and 4 Ohms in bridged class d full range modes. Input sensitivity is 200mV-6V, high and low, and channel separation is 12 decimals. Construction details: Material: Plastic; Color: White. Physical size: Dimensions (L x W x H): 13.75 x 9.75 x 3.75 inches. Weight: 5.90 pounds.
