Helix 4-channel amplifier with integrated active crossover M FOUR

HELIX M FOUR

If you like to rev up your front and rear speakers, the M FOUR will be exactly the right "tool" to do so. With generously 100 Watts RMS per channel into both 4 Ohms and 2 Ohms load this amp will heat up your voice coils in no time despite its super-compact dimensions. On the other hand the M FOUR stays totally cool thanks to the highly efficient Class D design topology. 3-channel or 2-channel configurations are possible as well, delivering up to 2 x 200 Watts RMS of clean and undistorted output power.

Needless to say that the M FOUR is equipped with a bunch of intelligent attributes like "start-stop capability" and our proprietary "ADEP" highlevel input so that it easily deals with all installation challenges of modern cars. Finally the extensive audio features will offer a sound quality at its best.
