Helix M FOUR
The Helix M-series amplifiers are incredibly small in size, yet feature-packed and powerful. This is made possible by advanced Class D technology.
The intelligent speaker level input works even in new cars thanks to the ADEP circuit. And this amplifier doesn't turn off at every traffic light thanks to Start&Stop compatibility. The crossover filter adjustment ranges are so wide that they can make crossovers from subwoofer to tweeter and everything in between.
Despite their small size, Helix's M-series products offer plenty of power and, above all, the excellent sound quality that Helix has been known for as a manufacturer for decades.
