The M3 has been our most popular high power amp for many years. Now, in its third generation the M3b continues to raise the bar in its power class. For the M3b we’ve upgraded the M3a’s power supply by increasing its current capability and efficiency. We’ve also upgraded the output section to deliver over 3800 Watts of clean power at standard alternator charging levels. We designed the M3b with stability not overrated specs in mind. This makes the M3b a go to amp when you need long term stability at the high power levels needed in extreme daily and competition installs.
