If you can put together IKEA furniture, you can install our Stage One in your BMW. Here’s why it’s so easy to install: The Stage One is designed from the ground up to be easy to install. Installation doesn’t involve complex wiring or modifications to your BMW. Just unbolt the factory speakers and install ours in place, plug in the factory connections, and play! (Some older E36 applications require slightly more work (a dab of glue here and there), but it’s always easy stuff!) Every Stage One comes with extremely detailed installation instructions with photos, or a step-by-step video install guide, or both, so you’ll know exactly what to do. Head here for more installation information on your particular BMW. Installation is so easy that we virtually never answer a phone call or email regarding the installation of the Stage One.
