Marine Grade compact Four Channel, 320 watt Powersports amplifier

MB Quart compact Two Channel, 400 watt Powersports amplifier with on-board equalization and simple instalation with quick release connectors. Class: Full Range Class D Variable Voltage: 0.2V9V Signal to Noise Ratio: >90dB Frequency Response: 20Hz-20kHz Crossover Frequency RangeCH1 & CH2: Switched HP/ Full Crossover Frequency RangeCH3 & CH4: Switched HP/ Full Bass Boost: 0-12dB 45Hz Power 2-Ohms: 4 x 80W Power 4-Ohms: 4 x 40W Total Channels: 4 Audio Inputs: RCA Power Terminal 12v/GND: Molex 10 ga Speaker Terminal Wire Gauge: Molex Plug Connector Fusing: 1 x 30 Amps Certifications: Marine & Powersports Dimensions: 3.70 X 5.51 X 1.77 in9.4 X 14.0 X 4.5 cm Weight: 2.16 lbs 0.98 kg Marine Grade Protection: YES Amplifiers are ABYC and ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray and moisture. Pre-Amp Circuitry: Q-Stasis Pre Amplifier Stage The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality Inputs: 2 Pair, RCA Nickel-Plated High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant Operation Mode: Four channel operation Flexible installation allows this amplifier to run in four channel or bridged mono mode. Crossover / Signal Shaping: Switched OFF / HP Complete control of amplifier signal, essential when using two or more amplifiers 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: Nickel-plated connections Nickel plated 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 f
