Phoenix Gold ZDAP-IZ1 – DSP upgrade for Isuzu with powerful and clear sound
Upgrade the sound experience in your Isuzu with the ZDAP-IZ1 DSP Power Up Kit – a complete Plug & Play solution developed for Isuzu models from 1993 onwards with factory-fitted basic audio systems. The kit delivers significantly improved sound quality with more power, better dynamics, and much greater clarity – all without changes to the car's original wiring harness.
The heart of the system is the ZDA4.8 Class A/B DSP amplifier with 4 x 70W RMS, which outperforms most factory amplifiers. Class A/B technology ensures a warmer and more natural sound than traditional Class D solutions, providing a more vibrant and detailed music experience. Even without DSP adjustments, a clear improvement is felt – and with the built-in DSP, the sound system can be precisely fine-tuned to your preferences.
Installation is simple and professional thanks to the included ZDT and ZDC cable sets. The ZDT connects directly behind the original head unit without cutting into the car's wires, ensuring stable power and clean signal transmission. The ZDC routes the connection to the DSP amplifier under the front seat, ensuring a discreet and neat installation.
OEM Impedance Simulation (OIS) ensures full compatibility with modern head units, while Input Priority retains all original functions and system sounds. With four DSP-configurable RCA outputs, the system can easily be expanded with, for example, a subwoofer for even more bass and punch.
