I sent my Promedia 5.1's in for repair almost 3 months ago, and they still haven't repaired them. When the Promedia 5.1's first came out, they all had a flaw in them which causes the amp to burn on fairly quickly. So I paid the $60 and shipped my sub to them, and 3 months later they keep giving me the same story that the parts are coming from China and there is a shipping problem... There any way I can complain and perhaps get a new sub? 3 months is a long ass time...
