Single Chassis Solution

Focal’s IBUS 20 powered 8” car subwoofer system complements your vehicle’s existing audio system perfectly – and for a few reasons. First, it’s designed to hide away under a seat or behind a truck’s rear seats (on the rear wall) so it doesn’t occupy your vehicle’s precious cargo space. Second, it ties into any audio system – an aftermarket radio or a factory-installed one. And lastly, it’s built to the exacting standards that we have come to expect from Focal. A built-in 75-watt amplifier powers the installed 8” subwoofer. Oh, and as a bonus, the subwoofer system comes with a wire remote volume knob so you can control the volume of the subwoofer independently from the rest of your sound system. You can look forward to accurate and engaging bass performance from this little guy.

Shallow-mount Subwoofer

How does Focal squeeze an 8” subwoofer into the compact IBUS 20 chassis? Simple: they use a high-performance shallow-mount subwoofer of their design and making. The engineers at Focal know how little room you’re willing to lose for something that can deliver some solid bass performance. For as small of a space that the IBUS 20 occupies, it can deliver some impressive low-frequency response. Get that bass response you crave without losing all of your available cargo area.

  • Powered 8” underseat/hideaway subwoofer system
