HELIX is Audiotec Fischer's flagship car audio brand, engineered and manufactured in Germany. Renowned worldwide for class-leading DSP amplifiers, dedicated DSP processors, and component speaker systems, HELIX is the choice of competition-winning installers and Sound Quality judges alike.
What sets HELIX apart in practice is the strength of its integrated DSP amplifiers — amps with a full digital signal processor built directly into the same chassis. Instead of running a separate DSP box cabled to your amps, a HELIX DSP amplifier gives you time alignment, parametric EQ and crossover control in one unit, wired straight to your speakers. It's a cleaner install, fewer points of failure, and — because the tuning happens right where the power is made — genuinely excellent sound quality for the space it takes up.
The current HELIX DSP amplifier range spans from compact factory-fit units to full flagship systems — see the full Car DSP Amplifiers range for every HELIX and MATCH model side by side, or browse the individual models below:
- HELIX AMPLIFY 206 DSP — a 6-channel, bridgeable amplifier with an 8-channel DSP built in, sized to fit tight factory locations. The natural starting point for a factory-speaker upgrade.
- HELIX NEXT V EIGHT DSP ULTIMATE — 8 channels of amplification with a 14-channel DSP and 12 high-level inputs, built for OEM-integrated systems that need serious processing power.
- HELIX P SIX DSP Ultimate — a premium 6-channel amplifier with 10-channel DSP output and 12/24V operation, at home in cars and select 24V platforms alike.
- HELIX V TWELVE DSP MK2 — 12 channels of amplification and a 14-channel DSP, for multi-way component systems that need real channel count.
- HELIX V EIGHTEEN DSP — the flagship: 18 channels of amplification and a 20-channel DSP, for reference-grade, no-compromise builds.
