About this item
Written by Crutchfield's Ken Nail
Add a kick to your BMW
Designed in Germany for the ultimate driving experience, you know your BMW will own the road. But if the bass from your factory sub system isn't cutting it, add some Focal audio tech to the mix. The ISUB BMW 4 fits perfectly into the sub enclosure of select BMW models, providing a dramatic boost in the low frequencies of your music. Focal utilizes much of the same technology that they employ in their audiophile-grade home speakers, so you'll enjoy your time behind the wheel even more.
Top-notch materials and design
The ISUB BMW 4 is designed to work perfectly with your existing BMW's amplifier. The Polyglass woofer provides neutral and accurate sound, while the butyl rubber surround holds up over the long haul. Integrated connectors hook up to your existing factory speaker plugs — no cutting or splicing required.
Installation Note:
In most cases, the new sub has the same screw hole pattern as the factory sub and is a perfect fit, but there are a few instances where the factory sub was glued in place and new screw holes need to be drilled in the plastic factory enclosure.
