JL Audio quality in a thin package

The PowerWedge CS112TG-TW3 truck-style enclosure pumps out signature JL Audio bass from a small sealed box. Install it anywhere that you might have a little room, like behind a seat or in the trunk, add an amp, and enjoy the extra depth that good bass will add to your system.    

Immense bass

JL Audio used their extensive engineering know-how to build a super-thin TW3 subwoofer that offers big performance. This PowerWedge handles up to 400 watts RMS, housing one 12" TW3 subwoofer that pounds out impressive low end. The enclosure is matched to the sub for optimum output, and the airtight sealed design delivers powerful, accurate bass.

JL Audio PowerWedgeCS112TG-TW3 Single 12" 2 Ohm Sealed Truck Sub

JL Audio made this sub to go behind a truck seat and deliver big bass.

Solid MDF enclosure

JL Audio uses state-of-the-art automated woodworking equipment to fabricate the high-quality MDF enclosure, then finishes it with rugged automotive carpeting, nickel-plated push terminals, and solid internal wiring. The enclosure is inspected by hand at the manufacturing facility in Florida to ensure that you get the bass that you expect from JL Audio.

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

Great Box For Trucks

Great sounding sub, box is made well and fits perfectly behind the drivers seat of my 02 Ford Lightning. I'm pushing it with a 500 watt RMS JL amp and it hits hard. My only complaint is that the screws used to hold the speaker to the box were too small and they wouldn't tighten the sub against the box, so when it hit, the sub would rattle a bit. I got slightly bigger screws and now the box is air tight.

Pros: Sounds great, fits in a tight space.

Cons: The screws that mount the sub to the box were a little too small.

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat.
