Focal understands that it's not easy to get bass into every vehicle. They built the IBus 20 powered subwoofer to address this issue, so folks with bass-deficient systems in space-challenged vehicles could add some low-end punch. At just under 3" tall, this sub can fit under or behind many seats in the spaces usually reserved for stale bits of food. Focal built its chassis out of rigid aluminum, so it'll take a beating while it provides an incredibly stable home for the 8" sub.

Big bass in a tight space
You'll finally hear bass lines and percussion in your music, as the IBus 20's 8" sub combines with a built-in 75-watt RMS amplifier to deliver some impressive bass. This sub comes with line-level inputs that'll connect to an aftermarket stereo, along with inputs that accept the speaker-level signal from a factory radio.
You can use the low-pass crossover to get your bass to mesh with the rest of your system, while the phase switch ensures that this sub is working together with the bass from your full-range speakers. Focal includes a wired remote control so you can adjust the bass with a flick of your wrist.
