- Key Specs
- Amplifier Class: D (An amplifier's mode of operation, specifically the conditions in which its electrical current flows for the duration of an audio signal, determines its class. Each class has its strengths and weaknesses when it comes to power efficiency, levels of crossover distortion, and overall sound quality.)
- Number Of Channels: 4
- Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)
- Low-Pass Crossover: Variable (Devices with this function allow only audio frequencies below a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)
- High-Pass Crossover: Variable (Devices with this function allow only audio frequencies above a chosen cut-off frequency to pass through to a speaker or sound system. A device may have a cut-off frequency predetermined by its manufacturer (fixed), multiple cut-off frequency options to choose from (selectable), or have the capability for the frequency to be configured by the user (variable).)

- Audio
- Number Of Channels: 4
- Minimum Frequency Response: 10 hertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The minimum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Maximum Frequency Response: 0.035 kilohertz (Describes the maximum range of frequencies or musical tones a product can reproduce, from very low tones to very high treble tones. The maximum frequency or musical tone the speaker can reproduce. High treble tones have higher frequencies while low tones and deep bass have lower frequencies.)
- Total Harmonic Distortion: 0.09 percent (Measurement of the harmonic sound distortion. The lower the percentage, the cleaner the sound.)
- Signal-to-Noise Ratio (SNR): 101 decibels (The ratio of the desired signal's strength to the level of background noise. A ratio higher than 1:1, which equates to greater than 0 decibels, indicates more signal than noise.)
- Bass Boost: Variable (Circuitry that boosts the bass response of the amplifier, improving audio reproduction enhancing the sound of low frequencies. Fixed boost means the level of bass response is preset, whereas variable boost allows the user to make adjustments.)

Enjoy rich sound with this four-channel MB Quart RA1-280.4 Reference Series car audio amplifier. The 280W output delivers enhanced sound quality, while the low-noise preamplifier circuit minimizes distortion. Featuring variable electronic crossovers, this MB Quart RA1-280.4 Reference Series car audio amplifier offers complete sound control, and the aluminum heat sink boosts cooling.
- 280W Maximum Power: Ensures robust audio.
- Low-Noise Preamplifier Circuit: A maximum low-voltage signal from the source unit comes into the amplifier circuit with minimal distortion.
- Nickel-Plated RCA Inputs: Erosion-resistant and high temperature impact-resistant with hex screw terminals that allow for secure connections.
- Electronic Equalizer: Control of amplifier output with on-board electronic crossover to tailor specific frequencies to speakers and subwoofers.
- Class SQ (Class D): 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.
- FLUID-FETS: Painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest-end home amplifiers.
- Aluminum Heat Sink: Quickly dissipates heat to allow the amplifier to run lower impedance for longer duration.
- Rugged MOSFET Pulse Width Modulation Power Supply: Allows the amplifier to produce efficient power without taxing the vehicle electrical system.
- Heavy-Duty Connections: Allows a secure electrical signal to pass into wiring and resist erosion, which adds longevity to the amplifier.
- Wired Bass Remote: Adjustments to bass frequencies can be made from the control mounted anywhere in the vehicle.
- Auto Turn-On: The amplifier turns 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.
- 0-9dB Bass Boost: Lets you add punchy bass to your music.
- 101dB Signal-to-Noise Ratio: Offers crisp sound.
- 0.09% THD (Total Harmonic Distortion): Provides clean sound.
- Variable Electronic Crossovers: Allow for complete control of the sound.
- 280W Maximum Power: Ensures robust audio.
