    Package Items

    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: 1-2 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.

    Frequently Asked Questions

    Will installing this package void my vehicle's factory warranty?

    No. Because our kits utilise genuine OEM-spec plug-and-play T-harnesses, there is zero cutting, splicing, or physical modification to your car's original electrical system. It preserves your vehicle's factory wiring entirely.

    Do I need professional audio tuning experience to make it sound good?

    Not at all. Your digital signal processor (DSP) arrives pre-loaded with a custom acoustic sound map engineered specifically for your vehicle's exact cabin dimensions and equipment. It is ready to perform right out of the box.

    What happens if I change my mind or want to sell my car later?

    Every single kit we sell is 100% completely reversible. You can easily unplug our hardware, remove any brackets, and return the car back to stock condition without leaving a trace — perfect for leased vehicles or preserving resale value.

    What is your return policy and warranty coverage?

    We offer a risk-free 30-day return policy for unused items and stand behind our gear with a comprehensive 1-year local Australian warranty on all products.

    Can I still retain my factory steering wheel controls and dash screens?

    Yes. Our system acts as an invisible power upgrade downstream. You retain 100% of your factory features, including steering wheel buttons, reverse cameras, Apple CarPlay, Android Auto, and factory warning chimes.
