Crown XS 1200 power amp. This amp is a BEAST. Crown quality and reliability, not to mention clean sound and tons of power. Specs. all @ 0.15% THD 8 ohms stereo, 650w. per.4 ohms stereo, 1100w. 2 ohms, (yup, it will drive that) 1600 wpc.In bridge mode 8 ohms 3000w. 4 ohms 2300 watts. This amp is older, but has very low hours. ( I estimate less than 30 ) A few minor scratches on the top, but the faceplate and back are super clean. MSRP on these was $999.00 . I will entertain offers. Thanks for looking !!
