Phoenix Gold ZDAP-BMW2

The ZDAP-BMW2 DSP Power Up Kit combines superior technology with user-friendly features, delivering an unparalleled audio upgrade. Whether you’re a casual listener or an audiophile, this kit provides the tools to achieve the perfect sound. Experience your music like never before, warmer, richer, and more dynamic.

Transform your audio experience with the Phoenix Gold ZDAP-BMW2 kit, with the Basic Sound System. This innovative Plug and Play kit addresses a common issue found in these systems: the front door speakers and underseat 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 underseat 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-BMW2 kit resolves this by separating the signal paths of the front door speakers, underseat woofers, and rear speakers, enabling a fully active configuration. This advanced setup allows precise tuning of frequency filters across the entire audio system. Each speaker can be finely calibrated to deliver optimal performance, dramatically reducing distortion, enhancing overall sound clarity, and unlocking the full potential of your vehicle’s sound system. The result is an immersive, balanced, and professional-grade audio experience like never before.

So transform your vehicle’s audio experience with the ZDAP-BMW2 DSP Power Up Kit, engineered to deliver exceptional sound quality. This plug-and-play kit includes a powerful 2x70W and 4x30W 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.

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.
• With these advanced features, you can tune your sound system to your preferences.

Phoenix Gold ZDBMW4CS 4” (100mm) 2-Way Component Speaker Kit

ZDBMW4CS

The Phoenix Gold ZDBMW4CS is a 2-way component speaker set designed specifically for BMW vehicles, offering a premium sound upgrade. It aims to improve clarity, control, and sound balance by addressing factory system limitations.

The ZDBMW4CS Speaker System Engineered Specifically For BMW Vehicles.

Experience premium sound quality and seamless installation with the Phoenix Gold ZDBMW4CS, speaker system engineered specifically for BMW vehicles. Designed with sound performance and installation versatility in mind, this kit redefines what a simple upgrade can do.

Engineered for Clarity and Control

The 4” midrange driver features an aluminium cone, chosen for its ability to deliver tight, punchy midbass and clear midrange tone reproduction – perfectly suited to bring vocals and instruments to life with accuracy and fun energy.

The 1” tweeter uses a silk dome to produce soft, smooth high frequencies, offering a refined, natural top end that enhances detail without harshness.

A dedicated 2-way crossover ensures each driver performs at its best, maintaining tonal balance and seamless integration between the midrange, tweeter and vehicle.

Smart Bass Blocker Function

In BMWs with the factory Basic Sound System, the underseat woofers and door speakers share the same signal. This means the small 4″ door speakers are forced to play deep bass tones they weren’t made for — often causing distortion and muddy sound.

The ZDBMW4CS includes an integrated Bass Blocker loop that filters out those low frequencies below 120Hz (-12dB/Oct). By doing this, it stops unwanted bass from reaching the midrange speakers, allowing them to play louder, clearer, and more accurately. The bass is then handled properly by the underseat woofers, giving you a balanced, distortion-free sound.

Precision Engineering Meets Simplicity

The ZDBMW4CS features a dual aluminium mounting bracket system, built for maximum rigidity and zero unwanted vibrations. Its innovative design ensures a perfect fit across multiple BMW configurations, regardless of which of the two OEM brackets your vehicle uses.
