Transform your vehicle’s audio experience with the ZDAP-PSA1 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, plug it in and enjoy an elevated listening experience.
The ZDA4.8 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 ZDA4.8 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 suit your preferences, no matter your music taste.
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-PSA1 is designed specifically for Citroën and Peugeot vehicles from 2005 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.
Software
Take control of your sound system with the free, user-friendly PC software (compatible with Windows 10 and 11). Connect via the included USB-B cable and unlock a suite of powerful tuning tools:
- 31-Band Parametric EQ (PEQ) for precise frequency adjustments
- Choose filter types (Bessel, Butterworth, Linkwitz-Riley) with adjustable slopes from -6dB to -48dB.
- Time alignment with a built-in delay calculator
