Description
Vibe OptiSound BMWF 4″ and 8″ Complete Speaker Upgrade Kit for BMW E-Series
A full plug-and-play 3-way upgrade for BMWs with the base audio system: 1″ silk-dome tweeters, 4″ mids and 8″ underseat subwoofers, all fitting the factory positions and wiring. It is built around the BMW4 front speakers, approved for the 1 Series E82/E87/E88 and 3 Series E90-E93. For HiFi or Harman Kardon systems Vibe recommend the BMWF2 kit instead, and Harman Kardon cars from 2019 use 8 Ohm subwoofers that are not compatible.
