About Helix

Helix is the core brand of Audiotec Fischer, the German family company founded in 1990 that has become the world reference for in-car digital signal processing — Helix DSPs are the tuning heart of more high-end installs than any other name. Alongside the processors sit outstanding German-engineered amplifiers (many with DSP built in) and precise, revealing speakers. Everything is developed and largely manufactured in Germany.

How to choose Helix products

Start with the speakers: the Helix Compose range is shaped to fit factory positions, with tiers from BASIC to the flagship i7. Then pick how you will drive them. A DSP amplifier such as the M Six DSP combines amplification and tuning in one unit, which is ideal for upgrading a factory system. Larger builds can pair a standalone processor with separate amplifiers. Add an IQ or IK subwoofer for full-range bass. See all DSP amplifiers to compare.
