{"product_id":"speaker-upgrade","title":"Speaker Upgrade","description":"The Bavsound Speaker Upgrade is a premium audio enhancement kit designed to elevate the sound quality in select BMW E39 models. This Stage One upgrade replaces your factory speakers with meticulously tuned components that deliver exceptional clarity, detail, and richness. You can expect a noticeable improvement with tighter, punchier bass and crystal-clear treble that plays much louder than the stock system. The kit is engineered with ultra-premium materials, including woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters, ensuring high-fidelity sound.\n\nInstallation is straightforward thanks to its 100% plug-and-play design, allowing for a DIY installation with an OEM finish. This upgrade is compatible with both factory and BavSound amplifiers and subwoofers, providing flexibility for further audio system enhancements. BavSound offers a 100-day in-car trial and a 4-year warranty for this product.\n\nThis speaker upgrade is specifically designed for select 1997-2003 BMW E39 models, including the 525i, 528i, 530i, 540i, and M5. It is not compatible with the M-audio system due to a higher number of speakers in that configuration.","brand":"Bavsound","offers":[{"title":"Default Title","offer_id":52687066759480,"sku":"BSD-E39","price":499.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661169630.jpg?v=1784880021","url":"https:\/\/store.motormia.co\/products\/speaker-upgrade","provider":"MOTORMIA","version":"1.0","type":"link"}
