Active or passive sub box?

Active subwoofer enclosures have the amplifier built in, so they need only power, earth, remote and a signal feed. They are the simplest bass upgrade and work with most factory stereos via a line output converter. Passive sub boxes pair with a separate amplifier for more headroom and more choice.

Sealed or ported?

Sealed enclosures give tight, accurate bass from a smaller box. Ported enclosures play louder from the same power and suit larger boots.

Space-saving subwoofers

Short on boot space? Under-seat subwoofers and spare-wheel subwoofers add real bass without losing luggage room.

Browse individual car subwoofers, or have your system fitted with our car audio installation service at our Beeston, Nottingham workshop.

Sub Enclosures FAQs

Q: Will an active subwoofer work with my factory stereo?

A: Usually, yes. Many active subs accept speaker-level inputs, or you can add a line output converter to create an RCA signal.

Q: What size sub box do I need?

A: Measure your boot or under-seat space first. Under-seat units suit small cars and vans, while 10" and 12" boxes need more boot room.

Q: Can CEN install a sub box?

A: Yes. We can supply and fit active and passive sub enclosures, including wiring, at our Beeston workshop.
