i have a kenwood kac-x812d i was just about to put up in the classified section. It is a refurb, and when i hooked up power for the first time, the wire sparked and a little smoke came out from under the amp. Hooked it up, and it works. i have pics of the board and everything, and it doesn't seem to have any wrong marks. I can't guarantee full power, but i will guarantee not DOA. $100 shipped. lMK
