MB Quart RA1-1100.4 Reference 1100 Watt Amplifier - 4 x 275W @ 2 Ohms, 4 x 160W @ 4 Ohms

Product info: 4-channel car amplifier Low Noise Preamplifier Circuit Q-Stasis Pre Amplifier Stage: Maximum low voltage signal from the source unit comes into the amplifier circuit with minimal distortion. RCA Inputs Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant. High Level Inputs See Auto-Sense Feature Operation Mode 2 / 4 Channel Crossover Type Variable electronic crossovers allow for complete control of the sound. Electronic Equalizer Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers. Check specifications for specific frequencies for this amplifier. Class / Topology Class SQ: Multi-channel amplifiers utilize the unique MB Quart Class SQ topology. Matched with Q-Stasis the sonic accuracy and clarity exceeds standard Class D amplifiers. Output Device Technology FLUID-FETS: MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers. Heat Sink Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration. Power Supply Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to produce efficient power without taxing the vehicle electrical system. Output Connections Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier. Connection Type Secure connection for all power, ground and speaker connections. Auto Turn-On DC SIGNAL SENSE: The DC SIGNAL SENSE switch will allow the amp to turn on when a signal is received on the RCA inputs, so an amplifier remote turn on wire is not needed to turn on the amplifier. This feature can also be turned off.
