Our take on the Pioneer UD-SW80D

Pioneer built their UD-SW80D 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 5-1/2" 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 .15 cubic feet of air space for a single 8" shallow subwoofer. Pioneer recommends installing the TS-SW841D 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.

Crutchfield Customer Review (What's this?)

I have a suburban with the subwoofer in the drivers side rear quarter. Terrible place for a speaker at all, let alone a sub. So, I decided to put it in an enclosure under the drivers side middle row seat. This enclosure was the right item. It doesn't even need to be strapped down. The bass response is excellent. Much, much better that the original location and enclosure. Quality construction, perfect fit, and no hassle install I would definitely recommend this box if you need a lot of sound in a tight space.

Pros: Easy install, fits in tight spaces. quality construction.

Cons: none

Compatibility: This enclosure is designed for a single Pioneer 8" shallow-mount component subwoofer, TS-SW841D (item number 130SW841D, sold separately).

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-SW841D. The UD-SW80D 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.
