The ZDA6.8 is a high-performance 6-channel amplifier with 8 DSP-configurable outputs, delivering 260W RMS (520W MAX) of power to elevate your vehicle’s audio experience. Engineered with Class A/B technology, it provides exceptional sound clarity and warmth, making it ideal for both standalone installations and plug-and-play setups with seamless OEM integration. Equipped with an easy-to-use built-in DSP, the ZDA6.8 provides precise sound tuning for enhanced audio performance and a fully customizable listening experience. Its Bluetooth V5.0 connectivity allows for direct music streaming, enabling it to function as a standalone head unit or bypass your factory system to deliver superior sound quality while retaining full OEM functionality. With a focus on sound quality and flexibility, the ZDA6.8 is the perfect solution for custom and OEM audio upgrades. 

Plug and Play Optimised 

The ZDA6.8 is optimized for use in plug-and-play installations, making it a perfect fit for seamless integration. Featuring Molex connectors, it pairs effortlessly with Phoenix Gold ZDT- and ZDC-harnesses, enabling quick and damage-free installation across a wide range of vehicles without the need for cutting or modifying wires.
With advanced features like Auto Turn-On, OEM Impedance Simulation (OIS), Start-Stop compatibility, and Input Priority, the ZDA6.8 is specifically designed to provide the best performance and functionality for OEM integration. 

The ZDA6.8 DSP Amplifier redefines in-car sound quality at this price point, outshining the standard factory-installed amplifiers. Unlike the typical Class D technology found in similar products, the ZDA6.8 employs Class A/B technology, delivering a warmer, more natural sound that brings your music to life. Even without DSP adjustments, the sound quality is significantly enhanced. However, the built-in DSP takes it further, allowing you to fine-tune your vehicle’s audio system to suite your preferences, no matter your music taste. 

OIS – OEM Impedance Simulation

The ZDA6.8 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 ZDA6.8 doesn’t stop at upgrading your system—it also enables expansion. With two free DSP-configurable RCA outputs (Channels 7-8), 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.
