ZDAP-ISO5 Plug & Play DSP Kit ISo 1990>

Transform your vehicle’s audio experience with the ZDAP-ISO5 DSP Power Up Kit, designed to deliver exceptional sound quality. This plug-and-play kit includes a powerful 4x70W RMS Class A/B DSP amplifier and all necessary premium-quality harnesses for seamless installation and maximum performance. No vehicle modifications are required—just plug it in and enjoy an enhanced listening experience.

ZDA4.8 – DSP Amplifier

The ZDA4.8 DSP amplifier sets a new standard for in-car audio, outperforming factory-installed amplifiers. Unlike the common Class D amplifiers used in similar products, the ZDA4.8 uses Class A/B technology for a warmer and more natural sound. Even without DSP adjustments, the sound quality is significantly improved. However, the built-in DSP functionality allows you to fine-tune your audio system to match your preferences, regardless of your music taste.

ZDC-ISO5 Harness

This harness is designed to simplify your audio upgrade, allowing seamless integration for vehicles with ISO connectors. With a length of 5.2 meters, the ZDC-ISO5 runs from behind your vehicle’s head unit all the way to the trunk, providing greater flexibility for custom audio installations.

Vehicle Compatibility

ZDAP-ISO5 is specifically designed for vehicles with ISO connectors and is also compatible with our ZDT T-harnesses. For a detailed list of compatible models, see our Vehicle Application List.

Technical Specifications & Features

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 preserves your vehicle’s OEM functionality and prevents potential issues with plug-and-play installations.

Input Priority – Intelligent Source Selection

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

DSP Outputs

The ZDA4.8 DSP amplifier allows for system expansion:

• Four DSP-configurable RCA outputs (Channels 5-8)
• Ability to connect additional amplifiers, such as a subwoofer amplifier
• Full optimization through DSP software
• Advanced settings for delay, filters, and equalization for optimal performance

Advanced DSP Software

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

• 31-band Parametric EQ (PEQ) for precise frequency adjustments
• Selectable filter types (Bessel, Butterworth, Linkwitz-Riley) with adjustable slopes from -6dB to -48dB
• Time alignment with a built-in delay calculator
• Custom channel routing
• Advanced linking options for copying or relating channels
