Every aspect, from installation to performance, is simplified with 100% plug-and-play functionality, making the transition seamless and leaving you with nothing but exceptional sound quality. The Stage One speaker package replaces every speaker in your BMW (excluding subs) and includes all necessary components, except for basic tools, for a hassle-free upgrade.
