Audiotec Fischer, the German Engineers behind BRAX, HELIX, and MATCH

Vehicle Specific Engineered Audio Solutions designed and engineered by Trail Seven with products curated from Audiotec Fischer; vehicle-specific audio and upgrade bundles — factory-clean installs with far-from-factory performance. We've collaborated with MSC, North America's exclusive distribution Partner for Audiotec Fischer to bring you undisputed class leading Plug and Play Audio Bundles.

What that means for you:  Every bundle arrives pre-wired and pre-tuned — no fitment guesswork, no piecing components together. You get reference-grade, made-in-Germany sound; we handle the integration. That's Trail Seven!

WHO IS AUDIOTEC FISCHER?

WHO IS AUDIOTEC FISCHER?

Audiotec Fischer is a German manufacturer of high-end car audio — and one of the world's leading names in digital signal processing (DSP). Every product is developed and built in-house in Germany, from circuit design to final measurement. That control is how a compact amplifier or processor delivers sound quality that once demanded a rack of home hi-fi gear.

FOUNDED ON ONE AUDIOPHILE MOMENT

FOUNDED ON ONE AUDIOPHILE MOMENT

In 1990, Heinz and Gudrun Fischer set out to recreate the emotion of a live concert inside a car. As a musician and hi-fi enthusiast, Heinz understood that music is more than volume — it is space, rhythm, and intimacy. Delivering it faithfully inside a vehicle's imperfect acoustics demanded uncompromising engineering and full control of every step. Three decades later, that founding vision still drives every BRAX, HELIX, and MATCH product.

WHY AUDIOTEC FISCHER

Three decades of in-house research, engineered and manufactured in Germany.

DSP done right — reference-grade digital signal processing tunes each system to the vehicle, not to a generic curve.
Built, not just assembled — hand-selected components and separately stabilized power supplies keep the output clean under load.
One tuning platform — the free DSP PC-Tool drives BRAX, HELIX, and MATCH through the same interface.
Future-proof — ACO-based processors keep gaining features through free software updates.
Made to last — repairable, upgradable, and backed by a lifetime warranty on BRAX electronics.

BRAX — THE REFERENCE

BRAX — THE REFERENCE

BRAX is the ceiling. Hand-built and hand-matched in Germany for listeners who want the last tenth of a percent — audiophile amplifiers and processors with the measurements to prove it, backed by a lifetime warranty on the electronics. When the goal is uncompromising sound, BRAX is the answer.

HELIX — PERFORMANCE, TUNED

HELIX — PERFORMANCE, TUNED

HELIX is the enthusiast's toolkit: DSP amplifiers, standalone sound processors, and the COMPOSE speaker platform, powered by Ultra HD Class D technology. It hands you — or your installer — complete control of the tune, at every budget.

MATCH — UPGRADE, DON'T REPLACE

MATCH — UPGRADE, DON'T REPLACE

MATCH is the smartest way to transform your factory system instead of tearing it out. It's engineered to work with your original head unit — you keep the screen, the steering-wheel controls, and every factory feature — while its built-in DSP corrects the factory signal and drives direct-fit, OEM-upgrade speakers. It's a massive leap over stock, and the most affordable way into Audiotec Fischer's German engineering.
