MB Quart Reference series five channel car audio amplifier featuring innovative sound quality and power technology to run four full range channel and a subwoofer channel. The RA1-710.5 is a 700 watt 1 ohm stable (channel 5 only) 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.

|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.
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.
2 / 4 / 5 Channel
Variable electronic crossovers allow for complete control of the sound.
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|
Innovative use of Class SQ (Class D) for full range and a Class Q1 (Class-D) amplifier to drive the subwoofer frequencies.
|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.
Aluminum: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to produce efficient power without taxing the vehicle electrical system.
Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.
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.
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.
