ZEEKR 7X Sound Pro Reference Audio UPGRADE PACKAGE (Preconfigured DSP + A²B PNP Integration)

$4,399.00

ZEEKR 7X 21-Speaker Sound Pro Compatible Audio Upgrade | Vehicle-Specific DSP Integration | Preconfigured OSCA Tune | A²B Plug-and-Play Integration

The 21-speaker ZEEKR Sound Pro system provides an impressive foundation, combining a sophisticated multi-speaker layout with a highly integrated factory audio architecture. However, like any OEM system, its final performance is shaped by factory processing and a calibration designed to satisfy a broad range of listeners and seating positions. For enthusiasts looking for proper musical accuracy, there is still room to improve soundstage focus, vocal placement, tonal balance, detail and overall system control.

Our ZEEKR 7X Sound Pro Upgrade Package is designed to take that factory system further rather than replace what already works well. Using advanced Goldhorn DSP amplification, vehicle-specific integration and an OSCA-developed calibration, the package provides greater control over how the existing 21-speaker system performs. The DSP is supplied preconfigured with a dedicated all-seat tune, developed around the ZEEKR 7X cabin and factory Sound Pro architecture. The result is a more focused, balanced and natural presentation, with improved imaging, clearer vocals, greater separation and more controlled low-frequency performance while maintaining the integrated character of the original system.

What’s Included

  • 1 × Goldhorn AB218 DSP Amplifier
  • 1 × Goldhorn A²B Plug-and-Play Harness – 1.5m: Vehicle-specific integration with the factory digital audio network.
  • 1 × OFC Power Wiring Kit: Includes fuse and terminated cabling to suit ZEEKR 7X and AB218 DSP amplifier, to connect to low-voltage battery under passenger seat.
  • 1 × set of 0.5m Harmonic Harmony Octave RCA Cables: Provides spatial clarity and fast transient response for the input signal.
  • 1 × Preconfigured DSP Setup: DSP software supplied preconfigured, including an OSCA-certified driver-seat audio tune, that is enjoyable for all passengers as well.
  • 1 × ZEEKR-Compatible Interior Trim Clip Pack: Replacement clips supplied to support a clean installation.

Key Features
  • Designed for Zeekr Sound Pro: Developed specifically around the factory 21-speaker premium audio system.

  • Refined Tonal Balance: Greater control over the system's frequency response for a smoother and more natural presentation.
  • Tighter Bass Control: Improves low-frequency definition, timing and integration with the rest of the system.

  • Complete System Approach: DSP integration, amplification, tuning and vehicle-specific hardware are developed to work together as one solution.
System Overview

Engineered specifically for Australian-delivered Zeekr 7X vehicles equipped with the 21-speaker Sound Pro system. The vehicle-specific Goldhorn DSP integration interfaces with the factory audio architecture while retaining the OEM speaker layout, then applies controlled signal routing, channel-level gain structure, equalisation, crossover management and time alignment through an OSCA-developed configuration.

The DSP is supplied preloaded with the required setup and driver-seat calibration, while the dedicated integration harness, fused OFC power wiring, high-end RCA cables and mounting hardware are specified for the vehicle to support a consistent installation. The result is a properly integrated DSP platform with greater control over staging, tonal balance, channel behaviour and low-frequency integration without replacing the core Sound Pro hardware.

Who This Is For

This package is designed for Australian-delivered ZEEKR 7X owners with the factory 21-speaker ZEEKR Sound Pro system who want greater control, accuracy and refinement from the existing premium audio system. It is currently compatible with:

  • Zeekr 7X Long Range RWD – 21-Speaker Sound Pro
  • Zeekr 7X Performance AWD – 21-Speaker Sound Pro

*This package is currently not compatible with the standard 10-speaker ZEEKR 7X RWD system. Contact us directly if you require upgrade solution for this version.

Why Choose OSCA EV Packages

Modern EV platforms require a different approach to audio, one that most traditional upgrade methods weren’t designed for. OSCA is among the first in Australia to develop high-end, platform-specific EV audio systems built around proper signal integration, DSP-controlled architecture, and real-world installation requirements. These packages are not adapted from older workflows or generic solutions. They are developed specifically for modern vehicles, with a focus on system behaviour, integration, and consistent performance. As EV platforms continue to evolve, we are actively working at the forefront of how these systems are understood, designed, and implemented.

Installation / Technical Notes

FAQs

Will this upgrade work with the factory sound system?

Yes. OSCA upgrade packages are specifically designed to integrate with the existing OEM audio system using native A2B signal integration.

Do you cut any factory wiring?

No. This is a plug-and-play installation with no factory wire cutting.

Will factory features still work?

Yes. Key built-in functions such as steering wheel controls and active noise cancellation remain operational.

Will this void my warranty?

Because the installation is plug and play and does not require cutting factory wiring, it is designed to avoid the common risks associated with invasive aftermarket installs. For formal warranty interpretation, the final decision always sits with the manufacturer or dealer.

What is the main improvement over stock?

The biggest differences are better soundstage height, clearer vocals, more controlled bass, and a more refined overall presentation. The sound feels less trapped in the doors and more properly placed in the cabin.

Is this just a louder version of the factory system?

No. It will improve output, but the real gain is in control, staging, clarity, and balance. It sounds more complete, not just louder.

How long does installation take?

Installation is relatively fast compared with a conventional custom system because the package is designed for seamless integration (usually no more than 1 day). Exact timing can be confirmed at booking.

Important Compatibility & Installation Information

  • OSCA EV Audio Upgrade Packages are aftermarket, vehicle-specific integration solutions. They are not tool-free or no-skill accessories.
  • Plug-and-play integration refers to connector-based integration with the factory audio system. Installation may still require interior trim removal, secure equipment mounting, correctly fused 12-volt power and earth connections, cable routing and vehicle-system awareness.
  • Vehicle compatibility is specific to the make, model, variant and factory audio configuration identified in each package listing. OSCA packages are developed and validated for the specified Australian-delivered vehicles and audio systems only.
  • Compatibility with other markets, vehicle configurations, existing audio modifications, replacement speakers or unlisted variants is not confirmed unless approved by OSCA in writing.
  • Professional installation by an authorised Goldhorn dealer or suitably qualified automotive audio technician is strongly recommended. Self-installation should only be attempted by individuals competent in vehicle trim removal, protected 12-volt electrical systems, wiring diagrams and the identification and avoidance of high-voltage and SRS components.
  • Do not attempt self-installation unless you can safely meet all applicable installation requirements.
  • OSCA DSP calibration must not be reset, overwritten or modified by unqualified individuals. Changes to signal routing, gain, crossovers, equalisation, polarity, delay, protective limits, firmware or output allocation may compromise system performance, disable audio functions or damage factory and aftermarket equipment.
  • Manufacturer independence: OSCA EV Audio Upgrade Packages are independent aftermarket solutions and are not manufactured, approved or warranted by the respective vehicle manufacturers or factory audio system suppliers, unless expressly stated otherwise.
  • Please review the full Compatibility, Installation and Warranty Conditions, along with the vehicle-specific product information, before ordering.
