Power Output & Configuration

The Autotek MM1020.4 Mean Machine is a four-channel Class AB car amplifier rated for 1000 watts maximum power. It delivers 125 watts RMS per channel at 4 ohms and 250 watts RMS per channel at 2 ohms. When bridged into two channels, each channel produces 500 watts RMS at 4 ohms.

Ideal System Fit

This amplifier suits installations that need clean Class AB sound across four speakers or a two-channel bridged setup for subwoofers. It is not for systems requiring Class D efficiency, mono-block topology, or built-in DSP and time-alignment features.

Deciding Specification

The 90 dB signal-to-noise ratio defines the noise floor you will hear at idle and low volumes. If your front-stage demands a quieter background than this figure allows, a different amplifier is required.

Questions about this item

How often should the Class AB output stage be checked or serviced?

Class AB amplifiers have no user-serviceable internal parts; keep the heatsink fins clear of dust and verify that power and speaker connections stay tight.

What limits continuous output on the 1000W Mean Machine?

Thermal protection engages when the heatsink temperature exceeds the safe threshold, reducing power until the amp cools.

How hot and loud does the amp get during all-day play?

The Class AB design draws significant current and produces noticeable heat; the chassis becomes hot to the touch while the internal fan runs continuously.
