Upgrade your BMW’s audio experience with the Phoenix Gold ZDAP-BMW4 DSP Power Up kit, designed specifically for BMW vehicles equipped with the HiFi Sound System (676) manufactured before mid-2019. The ZDAP-BMW4 kit unlocks the full potential of your vehicle’s sound system. KeyBenefits Enhanced Performance: The ZDA6.8 DSP amplifier delivers higher power output, increasing the dynamic range and overall volume capability of your system. Superior Sound Quality: Featuring Class A/B technology, the ZDA6.8 amplifier significantly improves clarity and fidelity, creating a richer, more immersive audio experience. Plug & Play Installation: Simply disconnect the OEM amplifier connector, attach it to the included ZDC-BMW1 harness, connect the harness to your ZDA6.8 DSP amplifier, and you’re ready to enjoy upgraded sound. With the ZDAP-BMW4 you will experience louder, clearer, and more detailed audio in your BMW. This simple upgrade transforms your car’s factory sound system into a high-performance audio solution. ZDAP-BMW4 Note: When using the ZDAP-BMW4 kit, the center speaker output will no longer be active. However, this setup delivers 2x 70W to the underseat woofers, enhancing bass performance and overall sound dynamics. For those who prefer center speaker amplification with reduced power to the underseat woofers, use ZDAP-BMW3 instead. ZDA6.8 – DSP Amplifier The ZDA6.8 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 ZDA6.8 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. OIS - OEM Impedance Simulation The ZDA6.8 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 ZDA6.8 doesn’t stop at upgrading your system—it also enables expansion. With two free DSP-configurable RCA outputs (Channels 7-8), 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 Fully custom channel routing Custom link options (Copy or Relate) With these advanced features, you can tune your sound system to your preferences.
