HELIX M FOUR 24 Volt Edition 4 Channel Digital Amplifier | 100W x 4 2Ω Stable
Commercial Power. Compact Design.
Experience reliable 24V amplification with HELIX M FOUR 24V Edition's Class D efficiency—delivering 100W RMS per channel at both 4Ω and 2Ω loads with smart high-level input featuring ADEP circuit protection.
If you like to rev up your front and rear speakers, the M FOUR - 24V Edition 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 - 24V Edition 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 - 24V Edition 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.
