This Crown XLS 2500 2500 watt RMS amp is in 9 condition. Because it is missing a gain knob. Otherwise it is in almost mint condition. The missing knob part works fine. And if you bridge the amp you won't even use the second gain knob just the first one. It works flawlessly. And will power any subwoofer well. The date on the amp is 12-16-2014. Asking $450 shipped.
