Autotek MEAN MACHINE series of car audio amplifiers bring extreme power with PRO-FI™ High Speed MOSFETS and high sound quality with minimum distortion levels. The MM4020.4 features 4000 watts of power in a bridgeable 4 channel Class A/B amplifier with larger heatsink providing very musical bass with dramatically reduced noise. The amplifier can be run from the “output” RCA connections which minimize the need for additional cables running the length of the vehicle.

Proposition 65 Notice WARNING: Cancer and Reproductive Harm -
Low Noise Preamplifier Circuit

Maximum low voltage signal from the source unit comes into the amplifier through a low voltage circuit which delivers minimal distortion through the amplification process.

RCA Inputs

RCA inputs and outputs provide the highest sound quality connection.

High Level Inputs

High level inputs easily tie into OEM audio systems that do not offer RCA output. Molex connector is included.

Operation Mode

4 channel operation mode allows either stereo or mono bridged operation.

Crossover Type

Switched FULL/LPF/HPF for complete control of amplifier signal which is essential when using two or more amplifiers.

Electronic Equalizer

Electronic equalizer provides control of amplifier output with onboard electronic crossover to tailor specific frequencies to speakers and subwoofers.

Class / Topology

Class A/B amplifiers have larger heatsinks with very musical bass.

Output Device Technology

MEAN MACHINE'S ROAD WORTHY™ TCID (Twin Coil Isolation Design) and PRO-FI™ High Speed MOSFETS bring extreme power with high sound quality and minimum distortion levels.

Heat Sink

Heavy-duty aluminum alloy heatsink with illuminated connectors provide a blue wash of light from the heatsink underside.

Power Supply

High energy PWM (Pulse Width Modulated) power supply provides MAXXimum power with minimal electrical impact.

Output Connections

Nickel-plated brass connectionwith hex set screw terminals allow for secure connection and resist erosion.

Connection Type

Angled, Allen Key connectors provide easy access for hand tools allowing a quick and secure connection.

Full-Range RCA Outputs for Signal Pass Through

Full-range signal pass through output allows additional amplifiers to be run from the "output" RCA connections which minimize the need for additional cables running the length of the vehicle. This can dramatically minimize noise.

LED System Protection Circuitry Diagnostics

Monitor overload and speaker short protection with illuminated indicators on the amplifier end panel.
