The KICKER Hideaway Compact Powered Subwoofer delivers surprising low frequency output from a remarkably small enclosure, setting a new standard in plug-and-play bass performance and convenience in a vehicle. At just over three inches high and nearly 14 inches long, the Hideaway combines a 150-watt amplifier and an 8-inch subwoofer to add thumping bass to any vehicle from the tightest locations.
