ZDAP-IZ1 Plug & Play DSP Kit Isuzu 1993>

Transform your vehicle’s audio experience with the ZDAP-IZ1 DSP Power Up Kit, engineered to deliver exceptional sound quality. This plug-and-play kit includes a powerful 4x70W RMS Class A/B DSP amplifier and all the necessary premium-quality harnesses for seamless installation and maximum performance. No vehicle modifications are required – simply 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 commonly used Class D amplifiers in similar products, the ZDA4.8 utilizes Class A/B technology, delivering a warmer and more natural sound.
Even without DSP adjustments, sound quality is significantly improved, but the built-in DSP function allows you to fine-tune and optimize your audio system according to your preferences, no matter your music style.

ZDC & ZDT Harness Benefits

• The ZDT harness seamlessly connects behind the OEM head unit without cutting any wires, ensuring stable power supply, clear signal transmission, and reduced noise, thanks to twisted cables and oversized power and ground wires.
• The ZDC harness extends the connection to the ZDA4.8 DSP amplifier under the front seat, allowing easy installation and improved audio performance.
• Together, they provide efficient integration and outstanding sound quality.

Fitment

The ZDAP-IZ1 is specifically designed for Isuzu vehicles from 1993 onward. For a detailed list of compatible models, refer to our Vehicle Application List.

Technical Specifications and 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, it preserves OEM functionality while preventing potential issues in plug-and-play installations.

Input Priority

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

DSP Outputs

The ZDA4.8 DSP amplifier enables system expansion:

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

Advanced DSP Software

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

• 31-band parametric EQ (PEQ) for precise frequency adjustment
• Selectable filter types (Bessel, Butterworth, Linkwitz-Riley) with adjustable slopes from -6dB to -48dB
• Time alignment with a 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.
