Rockville Wheel of BASS 8-Inch 500W Powered Car Subwoofer | Slim Cast Aluminum, Easy Install

Compact power for everyday listening

The Rockville Wheel of BASS 8 Inch is built to deliver deep, musical bass while occupying minimal space. At 3.15 inches tall, the slim enclosure can slide under a seat or sit in a compact trunk, making it a flexible upgrade for trucks, SUVs, and cars with limited cargo room.
