ZDA4.8 – DSP Amplifier

The ZDA4.8 DSP amplifier sets a new standard for in-car audio, surpassing factory-installed amplifiers by delivering warmer and more natural sound thanks to Class A/B technology.
Unlike conventional Class D amplifiers found in similar products, ZDA4.8 offers significantly improved sound quality, even without DSP adjustments. The built-in DSP functionality allows you to fine-tune your audio system to match your preferences, regardless of music style.

ZDC and ZDT Harnesses – Benefits

• The ZDT harness seamlessly connects behind the OEM head unit without cutting any wires, ensuring stable power delivery, clear signal transfer, and reduced noise thanks to twisted cables and reinforced power and ground wires.
• The ZDC harness extends the connection to the ZDA4.8 DSP amplifier under the front seat, allowing a clean installation and enhanced audio performance.
• Together, they provide efficient integration and exceptional sound quality.

Fitment

ZDAP-GM1 is specifically designed for Chevrolet, Opel, and Vauxhall from 2008 to 2019. For a detailed list of compatible models, refer to our Vehicle Application List.

Technical Specifications & Features

OIS – OEM Impedance Simulation

The ZDA4.8 is equipped with OEM Impedance Simulation (OIS) to ensure compatibility with modern head units and amplifiers. By simulating speaker impedance, OEM functionality is maintained, preventing potential issues with plug-and-play installations.

Input Priority – Automatic Source Selection

This feature enables seamless integration with your vehicle’s existing audio system. You can use low-level inputs or digital sources such as Bluetooth, Optical, or Coaxial, without losing important system sounds like parking sensors, alerts, and radio signals.
If your vehicle’s audio system has a high-pass filter that limits bass output, you can bypass this limitation by streaming audio directly to the DSP via Bluetooth, while still maintaining full OEM functionality.

DSP Outputs

The ZDA4.8 DSP amplifier allows for audio system expansion:

• Four DSP-configurable RCA outputs (channels 5-8)
• Ability to connect additional amplifiers, such as a subwoofer amplifier
• Full optimization via DSP software
• Delay settings, filters, and equalizer adjustments for optimal performance

Advanced DSP Software

Take full control of your sound system with the free and user-friendly PC software (Windows 10 & 11). Connect via the included USB-B cable and access advanced sound settings:

• 31-band parametric EQ (PEQ) for precise frequency adjustments
• Ability to select filter types (Bessel, Butterworth, Linkwitz-Riley) with adjustable slopes from -6dB to -48dB
• Time alignment with built-in delay calculator
• Fully customizable channel routing
• Advanced linking options to copy or relate channels

With these advanced features, you can fine-tune your audio system exactly to your preferences.
