Custom DSP car processor & amplifier «NITRO» HELIX

Professional modification of German Helix digital audio processors and DSP amplifiers (Audiotec Fischer) for car audio systems. These Helix devices possess such a high musical potential that they are among the best contenders for excellent sound post-upgrade. We simply take a superb foundation, eliminate the brand's factory cost-cutting, and significantly elevate the unit's class. The modification layout and pricing are tailored to each specific processor or DSP amplifier model. NB: I do not accept Class-AB car amplifiers or head units for modification — processors or integrated DSP amplifiers only!

My experience has proven an exceptionally high increase in sound quality from modifying HELIX components, whether it is a standalone multichannel DSP or an integrated DSP-amplifier unit. With properly modified models, you can easily surprise seasoned competitors in the SQ/SQL categories and even fight for top podium spots! Send in your upgrade request, and we will discuss what your specific HELIX is truly capable of.
