Researched Compatibility
The official Infiniti parts catalog identifies 28061-5NZ2B as the secondary amplifier used in the QX55 audio system. Verified applications include:
- 2022 Infiniti QX55
- 2023 Infiniti QX55
- 2024 Infiniti QX55
- 2025 Infiniti QX55
Applicable trims may include Luxe, Essential and Sensory, but compatibility remains dependent on the installed audio package. The official catalog lists this part alongside a separate primary amplifier, so buyers should confirm that they need the secondary amplifier specifically.
Additional QX50 Applications
Part 28061-5NZ2B also appears in the Infiniti catalog for certain QX50 configurations. The catalog describes the QX50 application as a Type 2 amplifier used during specific production periods, including approximately May 2020 through September 2021. Compatibility outside the QX55 should therefore be confirmed by VIN and production date.
A secondary OEM catalog lists broader potential coverage for selected 2019–2023 QX50 Autograph and Sensory models and 2022–2024 QX55 models. Because those ranges conflict with the production-date notes in Infiniti’s catalog, exact-number and VIN verification are essential.
Important Compatibility Notice
These vehicles can contain both primary and secondary amplifier modules. Similar-looking amplifiers with numbers such as 28061-5VG2A, 28061-5NY2A, 28061-5NZ2A or 28061-5NZ2C should not be assumed interchangeable.
Before purchasing:
- Match 28061-5NZ2B exactly with the original module.
- Confirm that the failed component is the secondary amplifier.
- Verify the factory audio package and vehicle production date.
- Compare all connectors, mounting points and housing details.
- Confirm fitment through an Infiniti dealer using the VIN.
- Do not rely solely on eBay’s automated compatibility chart.
- Do not purchase this module as a standard-to-Bose audio conversion.
Installation Information
Professional diagnosis and installation are recommended. Some replacement audio modules may require configuration, initialization or software procedures using Infiniti-compatible diagnostic equipment. Buyers should confirm those requirements with their installer before purchasing.
Disconnect the battery according to the factory service procedure before servicing electronic audio components.
