Features: MB QUART NA2 400.2 400w 2-Channel Amplifier Amp For Polaris/ATV/UTV/RZR/CART. Class / Topology: Full Range Class D - Highly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink.. Output Devices Technology: PWM MOSFET Power Supply - Stable power through the PC board with minimal heat generation. Heat Sink: Aluminum - Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration. Power Supply: Simpatico Coil Design - The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices. Output Connections: Quick Dissconect Wires, RCA Connections - Quickly remove amplifer when you are putting machine up for the winter of as a security precaution. Connections Type: Gold-plated connections - Gold-plated power, ground, speaker and RCA corrosion resistant connections. Diagnostics: Three-stage protection circuits - Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel. Marinized / Waterproof: Yes - Water resistant for durability in any environment. Specifications:. . Class: Full Range Class D. Variable Voltage: 0.2V~9V. Signal to Noise Ratio: >90dB.
