Product Description

Features & Specifications



MB Quart RA1-710.5 Reference 700 Watt 5 Channel Amplifier

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.

Power your music

MB Quart’s Reference Series RA1-710.5 five-channel amplifier will send 50 watts RMS to each of your front and rear speakers, and up to 350 watts RMS to a subwoofer, making sure you hear and feel your music over road and engine noise. Designed to power high-quality aftermarket drivers, like their Reference Series speakers and subwoofers, this Class D amplifier utilizes MB Quart’s unique Q-Stasis (Class SQ) circuitry to improve the accuracy and clarity of your music while giving it the oomph it needs for solid bass.

Versatile features

The amplifier’s features include speaker-level inputs with signal-sensing amp turn-on, so it’s ready to work in almost any system. High-pass filters shape the signal to fit your full-range speakers for their best-sounding output. A low-pass filter, subsonic filter, and a bass boost EQ on the subwoofer channel help dial in just the right amount of bass bump. A remote bass knob is included so you can control your subwoofer’s level from the front seat.

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 / 5 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

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.

Heat Sink

Aluminum: Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration.

Power Supply

Rugged MOSFET Pulse Width Modulation power supply: Allows amplifier to product 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.
