Package Items




Everything in Stage 1 & 2, plus the full genuine HELIX Ci3 speaker upgrade at every factory mounting location — front component set and rear component set. Trim removal tools and sound-deadening material included. The end-game before full custom fabrication.
Self-install, no experience needed. Genuine plug-and-play connectors, no cutting or soldering. Free trim removal tools included where needed, plus full install support. More resources are being developed. Typical install time: 3-5 hours.
On DSP tuning: your DSP does not come pre-tuned for your vehicle — for the best result, we strongly recommend running our free DSP Tuning Guide with the AMI Tuning Kit — it takes under an hour and uses Audiotec Fischer's own auto-tuning software.
