Show original supplier description

Designed specifically for E60/E61 Sedan and Wagon models equipped with the base audio system, this kit allows for a direct swap of your original speakers without altering your existing audio setup. These Stage One speakers utilize proven audio technologies, including woven fiberglass cones, butyl rubber surrounds, and silk composite tweeters. This construction results in higher quality sound with a wider range and more balanced reproduction of bass and treble, remaining distortion-free even at higher volumes. Installation is a simple, reversible process, often described as plug-and-play. You can unbolt your factory speakers, plug in the new Bavsound speakers, and enjoy the enhanced audio. The kit includes everything needed for installation, except basic tools. Bavsound offers a 100-day in-car trial and a 4-year limited warranty on these speaker upgrades. However, it is important to note that this kit is explicitly excluded for 1996-1999 BMW 3 Series / M3 models.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
