CP112-W0v3: Single 12W0v3 BassWedge, ported, 4 Ω
Enclosed subwoofer system with a single 12W0v3-4 subwoofer in a slot-ported BassWedge enclosure. Finished in dark grey automotive carpet, rated at 300W RMS, 4 Ω.
The slot-port runs along the bottom of the enclosure and fires on the same plane as the woofer, producing strong extension and smooth response. The port mouth is flared to minimise air-flow noise.
The BassWedge™ shape features extended sides so the enclosure can be positioned with the woofer firing outward or straight down, off the vehicle floor. It works equally well in forward or rear-firing installations, giving you flexibility to optimise loading for your vehicle.
- Finish: Dark grey, high-grade automotive carpet with "JL AUDIO" embroidery on the top edge and "Slot-Ported BassWedge™" embroidered on the port mouth
- Construction: MDF
- Recommended amplifier power: 75 – 300W

About the JL Audio CP112-W0V3
From our tech experts at CEN
A JL Audio 12 inch W0 subwoofer supplied in a BassWedge ported enclosure, handling 300w RMS. The box is built to the driver’s specification rather than to fit a shelf.
Who it suits
Drivers who want the result without commissioning a custom build. Ported enclosures play louder and dig deeper for the same power, at the cost of size.
Our tech experts advise
Match the amplifier to the enclosure’s rating rather than the driver’s headline figure, and secure the box properly: an unrestrained enclosure is dangerous in a crash. Installation is priced per vehicle, so get in touch with your make, model and year and we will confirm what it needs. See car audio installation.

Frequently Asked Questions
Q: Do I need an amplifier for this subwoofer?
A: Yes, unless it is an active (powered) subwoofer with a built-in amplifier. Passive subwoofers need an external amplifier matched to the RMS power and impedance shown in the Specification tab.
Q: What does RMS power mean?
A: RMS is the continuous power a subwoofer can handle, and it is the number that matters when matching an amplifier. Peak or max figures describe short bursts only. Match your amplifier output to the RMS rating in the Specification tab.
Q: Can CEN build or supply an enclosure and fit everything?
A: Yes. CEN supplies enclosures and offers professional installation from our Nottingham premises, including amplifier wiring. Contact us to discuss your build.
Q: Is the JL Audio CP112-W0v3 ready to use out of the box?
A: Yes. It is shipped wired and loaded with a 12W0v3-4 subwoofer and connects via a push-button terminal. You just need an amplifier delivering between 75 and 300W into 4 Ohm.
Q: Which way can the CP112-W0v3 be installed?
A: The BassWedge shape has extended sides, so it can be placed with the woofer firing out or straight down off the vehicle floor, and works in forward or rear-firing installations.
Q: Does the CP112-W0v3 come with a grille?
A: No, a grille is not included with this enclosure.
