I had the Memphis MC500D for less than a month....sold it- couldn't stand the audible THD @ 2ohms.....I went by word of mouth/budget too and disregarded its mediocre THD specs @ 4ohms, so my DVC doubled that distortion @ 2ohms......not for SQ thats for sure, if all you want to do is to get loud and nothing else, its for you- I was very disappointed i sold my Kicker ZR360 for it
