<font color='#000000'>I am looking for a single channel amplifer to drive my passive subwoofer. I built the sub using the Dayton MKII driver which is 4ohm and max wattage of around 400. I came across the M200 for only $299. I think to myself, wow, that is a good price for the wattage it puts out. Does anyone have anything good/bad to say about this amp? Thanks in advance, Paul.</font>
