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.
