Phoenix Gold ZDAP-BMW4 – Maximum Bass and Dynamics for BMW HiFi Sound System (676)
Upgrade the sound in your BMW with the Phoenix Gold ZDAP-BMW4 DSP Power Up Kit – developed for models with the HiFi Sound System (676) manufactured before mid-2019. The kit is designed to unleash the full potential of the car's original sound system and deliver a significantly more powerful and engaging sound experience.
The heart of the system is the ZDA6.8 Class A/B DSP amplifier, which provides higher power and improved dynamics. The result is a cleaner, more detailed, and vibrant reproduction with significantly better control over the entire frequency range. Installation is 100% Plug & Play – simply remove the original amplifier, connect the included ZDC-BMW1 cable set, and connect to the ZDA6.8. No coding or modifications are necessary.
When using the ZDAP-BMW4, the center speaker is deactivated, but in return, 2 x 70W are delivered directly to the bass units under the seats. This provides a significantly more powerful and precise bass reproduction as well as increased dynamics throughout the system. If an active center speaker is desired, the ZDAP-BMW3 is recommended as an alternative.
The built-in DSP provides full control with a 31-band parametric equalizer, adjustable filter types, and time correction. OEM Impedance Simulation (OIS) ensures full compatibility with the car's head unit, and Input Priority retains all original functions and system sounds.
