You want to upgrade the factory speakers in your BMW, but you're not interested in making modifications to your vehicle to get better sound. Focal's IFBMW-S system provides you with a huge improvement in sound quality by letting you replace the BMW's front door tweeters and woofers with a set of custom speakers that fit right into the factory locations and plug into the existing wiring. Once these speakers are installed, you'll experience more clarity, punchier midrange, and more detailed bass lines — without having to cut new holes or run new wiring.
This package comes with almost everything you need to improve the sound in your car dramatically. You'll find a pair of 4" Polyglass woofers, each in a custom frame that mount to your door perfectly — no adapter needed. You'll clip the two aluminum inverted dome tweeters directly to the factory tweeter grilles. Don't worry if you don't have the factory tweeters — Focal provides you custom tweeter mounts just in case. This system comes with BMW speaker plug connectors, so they plug right into the factory speaker wiring. You'll also find most of the tools needed for the installation in the box.
Sounds great with factory power
Focal designed this set of speakers to deliver superb sound, even when powered by the BMW 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.
