Underseat Subwoofers FAQs

Q: Are underseat subwoofers any good?

A: Yes, for filling out the bass a factory system lacks. They will not match a large boot sub for volume, but a good underseat sub makes music much fuller while keeping your boot free.

Q: Will an underseat subwoofer fit under my seat?

A: Measure the height and depth of the space under your seat and compare it with the sub's dimensions in the Specification tab. Seat runners and wiring can reduce the space, so leave a little clearance.

Q: Do underseat subwoofers need an amplifier?

A: Most are active, with the amplifier built in, so they only need power, earth, a remote and a signal. The plug and play BMW and Mini subs are passive and need an amplifier.

Q: Can I connect an underseat sub to my factory stereo?

A: Usually, yes. Many active underseat subs have speaker-level inputs, so they can take a signal from your existing speaker wiring.

Q: Can CEN fit an underseat subwoofer?

A: Yes. We supply and fit underseat subwoofers at our Beeston, Nottingham workshop.
