Transform your BMW’s audio experience with the Phoenix Gold ZDAP-BMW1 kit, specifically designed for BMW vehicles from 2005 to 2019 equipped with the Basic Sound System. This innovative Plug and Play kit addresses a common issue found in these systems: the front door speakers and under seat woofers are connected together, compromising sound quality and performance.
In the stock configuration, the small 4” door speakers are forced to handle lower bass frequencies, leading to distortion. Simultaneously, the under seat woofers are required to reproduce midrange and treble frequencies they were not designed to handle, further degrading the audio clarity. The result? A muddled and distorted sound profile that falls far short of your vehicle’s potential.
The ZDAP-BMW1 kit resolves this by separating the signal paths of the front door speakers and the under seat woofers, converting them into an active configuration. This setup allows for precise tuning of frequency filters, ensuring each speaker handles only the frequencies it’s designed for. This dramatically reduces distortion, improves overall sound clarity, and unlocks the full potential of your vehicle’s audio system.
So transform your vehicle’s audio experience with the ZDAP-BMW1 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.
ZDA4.8 – DSP Amplifier
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.
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
- Fully custom channel routing
- Custom link options (Copy or Relate)With these advanced features, you can tune your sound system to your preferences.
