Pioneer built their UD-SW100T subwoofer enclosure so you can get great bass in a truck where there's not a lot of space. This rugged enclosure comes in at 3-3/8" deep, so it'll fit behind most truck seats. Built with 5/8" medium-density fiberboard and covered in durable black carpet, this enclosure provides .35 cubic feet of air space for a single 10" shallow subwoofer. Pioneer recommends installing the TS-SW2501S4 subwoofer in this enclosure.

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

Product Highlights:

  • sealed truck-style enclosure for one 10" shallow subwoofer
  • 5/8" MDF (medium-density fiberboard) with black carpet covering
  • internal volume: 0.35 cubic feet
  • dimensions: 24"W x 12"H x 4-3/4"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why do I need an enclosure?

An enclosure is simply the box that houses your sub; sealed and ported enclosures are the most popular types. A sealed enclosure is usually smaller in size, sacrificing a little volume level to deliver more accurate bass. The ported enclosure features a vent which allows bass waves to escape from behind the mounted sub, augmenting the bass coming off the front of the sub. Ported boxes are louder, bigger, and a little less accurate. Every sub works best in the size and type of enclosure that's recommended by the manufacturer, so make sure you match your sub with the right box.

Features

Compatibility: This enclosure is designed for a single Pioneer 10" shallow-mount component subwoofer, TS-SW2501S4 (item number 130TSS2501, 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-SW2501S4. The wedge shaped UD-SW100T enclosure fits behind the seat of many pickup trucks. 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.

Awesome box

Crutchfield Customer Review (What's this?)

Fits great in the storage compartment in the back of my Tacoma Double Cab. Put a Fosgate low profile sub in and wow. Love it.

Pros: Low profile and great sound

Cons: None
