MB Quart RA1-300.1, Reference Mono Block Subwoofer Amplifier - 325 Watts

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.
