Rockford Fosgate T3-BMW2

Plug-n-play perfection

This Rockford Fosgate 4" 2-way component speaker system gives you a big sonic upgrade for your ultimate driving machine. Built exclusively for use in select 2008-10 BMW models, these speakers fit directly into your vehicle's speaker openings with BMW factory connectors that simplify installation.

BMW quality

Manufactured in Germany, this component system upholds the power and performance expectations you have for your car. The system's 4" woofer uses a tri-laminate fiber cone that is both light and stiff, ensuring precise bass and midrange articulation. A 1" silk dome tweeter handles the high-frequency range with impressive detail. You can drive this system with your BMW radio and hear excellent results, but these speakers will really shine when you add outboard amplification.

Installation note: To ensure that this direct-fit model is compatible with your BMW, please enter your vehicle information or call an Advisor at 1-888-955-6000.

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Product Research


Woofer Cones: The woofer cones are two layers of glass fiber sandwiched around a Nomex honeycomb core. The woofer frame is made from glass fiber reinforced poly-carbonate. The BMW factory wire harness plugs into one port on the woofer, and the included tweeter wire plugs into the other port.

Tweeters: The 1" silk dome tweeters use neodymium magnets and a glass fiber reinforced polyamide frame.

Crossovers: The crossovers are wired in-line with the included tweeter wire. One end of the wire is terminated with a single proprietary plug that fits a port on the midrange. The other end of the wire has two identical tweeter plugs, giving you two output level options; flat (labeled Reference) and +3 dB.

Klippel Optimized Components: For a driver to reproduce complex sounds accurately, the cone must move exactly the same distance and manner in both directions. The Klippel distortion analyzer, a device that uses a laser and sophisticated software to do large-scale analysis of drivers in motion, lets Rockford Fosgate optimize the speaker's motor structure, voice coil alignment, and suspension to yield the best possible performance.
