ZDAP-VAG1

ZDC- and ZDT- Harness Benefits
The ZDT- harness connects seamlessly behind the OEM head unit without cutting any wires, providing reliable power, clear signal transfer, and reduced noise thanks to its twisted cables and oversized power and ground wires.
The ZDC- harness extends this connection to the ZDA4.8 DSP Amplifier under the front seat, ensuring a clean installation and enhanced audio performance. Together, they deliver efficient integration and exceptional sound quality.

Fitment

The ZDAP-VAG1 is designed specifically for Audi, Seat and Volkswagen vehicles from 2010 onward. For a detailed list of compatible models, refer to our Vehicle Application List.

OIS - OEM Impedance Simulation

The ZDA4.8 is equipped with OEM Impedance Simulation (OIS), ensuring compatibility with modern head units and amplifiers. By simulating speaker impedance, it maintains the functionality of your vehicle's OEM head unit, preventing potential issues with plug-and-play installations.

Input Priority

The Input Priority feature ensures effortless integration with your vehicle’s OEM head unit. You can use low-level inputs or digital sources such as Bluetooth, Optical, or Coaxial, without losing vital system sounds like parking sensors, alerts, and radio signals. For instance, if your vehicle has a high-pass filter that limits bass output, you can bypass this limitation by streaming audio directly to the DSP via Bluetooth while maintaining full OEM functionality.

DSP Outputs

The ZDA4.8 doesn’t stop at upgrading your system—it also enables expansion. With four free DSP-configurable RCA outputs (Channels 5-8), you can connect additional amplifiers, such as a subwoofer amp, and fully optimize them using the DSP software. Delay settings, filters, and equalization options ensure top-tier performance for your additional components.
