MB Quart Reference series mono subwoofer car audio amplifier featuring innovative sound quality and power technology. The RA1-750.1 is a 750 watt 1 ohm stable car audio amplifier. Reference amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit. Bass remote is included.

General Features:

• 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
  Mono only
• 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 Q1 Mono (Class D): MB Quart's Class Q1 offers the efficiency of today's D-Class with increased engineering to focus on sound quality from the power supply through the output devices, the FLUID-FETS.
• 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.
• Bass Remote Included
  Included: Wired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle.
• 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.
