Our take on the Pioneer UD-SW120D

Pioneer built their UD-SW120D subwoofer enclosure so you can get great bass in a vehicle where there's not a lot of space. This rugged enclosure comes in at just 6-1/4" tall, so it'll fit under many seats or even under the overhang in some trunks. Built with 5/8" medium-density fiberboard and covered in durable black carpet, this enclosure provides .50 cubic feet of air space for a single 12" shallow subwoofer. Pioneer recommends installing the TS-SW3001S4 subwoofer in this enclosure.

Pioneer builds this sturdy box to deliver tight, accurate bass. Install a compatible sub, power up with a suitable amplifier, and you'll be ready to rock.

It's a great compact box. It was the perfect size to fit underneath the seat of my f-150.

Hands-on research

Product Research


Compatibility: This enclosure is designed for a single Pioneer 12" shallow-mount component subwoofer, TS-SW3001S4 (item number 130TSS3001, sold separately).

Note: Other brand subwoofers may also be compatible.

Materials: The box is constructed of 5/8" MDF (medium density fiberboard). MDF resists flexing and has anti-resonant qualities.

Design: Complementing the shallow subwoofer, this enclosure provides the smallest sealed box volume recommended for the TS-SW3001S4. The UD-SW120D enclosure will fit under the seat of many vehicles. The exterior is covered with black auto carpet.

Terminals: The spring post wire terminals, located on the side of the enclosure, will accept bare wire (up to 10 gauge), pin connectors, banana plugs, and dual banana plugs.

Brackets: Brackets (not included) are recommended for more secure mounting.
