MB Quart FA1-900.5

MB Quart Formula series five channel car audio amplifier featuring innovative sound quality and power technology to run four full range channel and a subwoofer channel. The FA1-900.5 is a 900 watt 1 ohm stable (channel 5 only) car audio amplifier. Formula 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.

Product Details:

  • FORMULA Series 5-Channel Class A/B + Class D Amplifier
  • RMS Power Output:
    • 500W x 1 @ 1 ohm (Channel 5 only)
    • 100W x 4 + 350W x 1 @ 2 ohm
    • 60W x 4 + 250W x 1 @ 4 ohm
  • 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.
  • Variable electronic crossovers allow for complete control of the sound
  • FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers.
  • Heavy duty heat-sink efficiently moves heat from the MOSFET where it can be cooled
  • Variable High Pass Crossover 12dB Per Octave(CH1 & CH 2 / CH3 & CH4): 50Hz - 250Hz (Variable)
