Focal Inside IBUS 2.1 Subwoofer

Bring a full 2.1 sound system to your vehicle with the Focal IBUS 2.1, an innovative all-in-one solution that integrates a flat active subwoofer with a 2-channel amplifier. This compact design allows you to reinforce bass while simultaneously powering your front speakers, creating a dynamic and well-balanced soundstage.

The 8-inch (20 cm) subwoofer, powered at 75W RMS, delivers deep and controlled bass (down to 45Hz), while the 2-channel amplifier outputs 2 × 55W RMS, ensuring your front speakers reproduce clear, powerful mids and highs.

With its ultra-slim aluminum enclosure, the IBUS 2.1 fits discreetly under a seat or in a trunk, without sacrificing cabin or storage space. Installation is simple thanks to the included Plug & Play ISO cable and dedicated power wiring. Additional features such as remote control, low- and high-level inputs, and robust heat dissipation make the IBUS 2.1 a reliable, performance-driven upgrade for any factory audio system.
