{"product_id":"audio-amplifier-for-bmw-3-4-series-f-chassis","title":"Audio Amplifier for BMW 3\/4 Series F-Chassis","description":"This Harman Kardon amplifier is a genuine OEM BMW part (9330057) designed for the Harman Kardon Surround Sound System in specific BMW F-series models, including the F30, F31, F32, F34, and F36. It plays a crucial role in amplifying audio signals, distributing frequencies, realizing the surround effect, and maintaining factory equalization settings for an immersive sound experience.\n\nThe amplifier ensures perfect integration with the vehicle's electrical architecture, correct connectors, and compatibility with the factory radio, head unit, and speaker wiring. By using this original module, communication with the vehicle's bus is maintained, along with correct audio configuration recognition and support for surround sound modes, without requiring harness modifications or additional adapters. This guarantees an acoustic consistency with the original BMW and Harman Kardon design, offering stable sound and avoiding software compatibility issues.\n\nThis unit is offered as a used part, providing an economical solution for repairing or restoring your vehicle's factory sound system. It is suitable for addressing issues such as no sound, channel dropouts, or audio module communication errors. Before installation, it is recommended to verify compatibility with your specific vehicle's equipment configuration and perform standard service procedures to ensure stable operation.\n\nCompatibility is critical for this amplifier. While it was removed from a 2014 BMW F32 435xi M Sport (VIN: WBA3R5C58EF785036), it may not work with all specific models, trims, or options. Buyers MUST confirm compatibility with a dealership by providing the part number, donor vehicle VIN, and their vehicle's VIN before purchasing.","brand":"Harman Kardon","offers":[{"title":"Default Title","offer_id":52688633692472,"sku":"9330057","price":430.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/663179655.webp?v=1784892115","url":"https:\/\/store.motormia.co\/products\/audio-amplifier-for-bmw-3-4-series-f-chassis","provider":"MOTORMIA","version":"1.0","type":"link"}
