This is a good looking and great sounding sealed box with two 12" JL Audio subs. It is a car audio box but I've been using it as a home theatre sub with a 450W external amp, as pictured. It gets LOUD! Works perfect; selling as downsizing. Amp is included in sale and is for home use; you'll need your own car amp setup if using the subs in a car. Dimensions: 32"L 22"W 16"H
