If you’re ready to take your system to the next level then the M4a is the tool for you. The M4a is based on the circuitry of our world renowned Z2-LV amps, and features a 6 transformer power supply. We designed the M4a to produce massive output with real world input voltage levels. This amp can deliver over 5,200 Watts RMS at 12V, over 7,000 Watts RMS at alternator charging levels, and has a dynamic power rating of over 9500 Watts! To make the M4a even sweeter our M Class heatsink enables the M4a to have one of the smallest footprints in its power class while maintaining maximum heat dissipation. This makes installing one, or more of these monster amps as easy as possible.

WARNING: The M4a is designed to work off real world input voltage levels (12-14v), but you’ll still need an upgraded charging system to realize the true potential of this beast. At maximum output level the M4a can require over 1000 amps of sustained/stable current. Failure to provide a stable power supply to the amp at the desired output level will often result in amplifier failure. This type of failure is not covered under warranty. So play it loud, but play it safe.
