New M FOUR now in 24V version!<br><br> The physical size of the Helix M-series amplifiers is really small, even though the feature list and power are large. This is possible thanks to advanced D-class technology. <br><br> The intelligent speaker-level input works even in new cars thanks to the ADEP circuit. And this amplifier doesn't shut down at every traffic light either, thanks to Start&Stop compatibility. The adjustment ranges of the crossover filters are so wide that they can be used to create crossovers from subwoofer to treble and everything in between. <br><br> Despite their small size, Helix's M-series models offer plenty of power and, above all, excellent sound quality when driving. Helix has been known as a manufacturer for decades.
