    first of all the 50 x 2 is not quite correct atleast not on my board. i only got about 40 watts but could have been my speaker ohms being 16 ohms. other than that great as a subwoofer for small 6 x 9 speaker kit. i did not have dc offset like the other reviewer but could be that i put a 4700 cap...
