The Crown XLS 2002 is a great little powered amplifier. It supplies 650 Watts stereo at 4 ohms, perfect for my passive set up! Crown can always be depended on for durability and reliability. One of my favorite features of this amp is that it is compact and lightweight, something you don't get from some of the older amplifiers produced; I'm not breaking my back just to carry a power amp. All and all a great buy and well worth the purchase. This amp has held up for the past year I've had it.
