Installation kit

BMW upgrade in about an hour

You love your BMW and you're not interested in replacing the factory receiver. Fair enough, but a sound upgrade is still possible, and it's oh-so-easy, thanks to Focal.

This IFBMW-C "Plug & Play" kit includes two 4'' 2-way speakers for select BMW X1 and Series 1, 3, and 5 models with speakers appearing only in the doors. Simply unfasten the door panels with the tools provided and remove the old speakers. The Focal speakers fit right into the factory locations and plug into the existing wiring, making installation a breeze.

What you're packin'

Each Focal coaxial speaker features a polyglass woofer for warm, natural sound, an inverted dome tweeter that delivers smoothness in the high frequencies, and a built-in passive crossover that provides seamless sound. Once these speakers are installed, you'll experience better clarity in vocals, punchier midrange, and more detailed bass lines — all without having to cut new holes or run new wiring.

Even better with aftermarket power

Focal designed this set of speakers to deliver superb sound, even when powered by the factory radio. But this system handles up to 40 watts RMS, so an aftermarket car stereo or an external amplifier will make these speakers sound even better.


    • two 4" coaxial speakers plus installation tools and clips
    • designed specifically for BMWs with speakers only in the doors
    • 100% plug and play in select BMW models makes for quick installation
    • significant results even without changing the OEM system
    • works with factory radio, aftermarket receiver, or outboard amp
    • 2-40 watts RMS power range (80 watts peak)
    • frequency response: 85-22,000 Hz
    • impedance: 4 ohms
    • sensitivity: 90.5 dB

    Product Research


    Polyglass Cone: The woofer cone has a cellulose pulp base and is coated with a uniform deposit of hollow glass microballs. The addition of the Polyglass layer significantly increases the cone's rigidity without adding much weight. This combination takes advantage of the accuracy and neutrality of the hard outer surface, but maintains the superior damping characteristics of the cellulose pulp.

    Surround: The woofers' rubber surrounds are resistant to ultraviolet rays, temperature extremes, and humidity, adding to the system's reliability and longevity.

    Inverted Dome Tweeter: The tweeters are inverted aluminum and magnesium domes, producing a broad sound stage.

    Crossovers: The included speaker wire has in-line crossovers for the woofers and tweeters. The crossover slopes are 18 dB/octave and the crossover point is 4 kHz.

    Product reviews from the Crutchfield Labs

    Russ, a Crutchfield employee, didn't like the lack of bass and poor high-frequency clarity in the "premium" system of his 2008 BMW 335i. He decided to try the Focal IFBMW-S and IFBMW-C custom-fit...
