I have 2 tens and 1200 watts total going to them. They sound good and I am pleased with their performance. I do have one concern though. When I have them up loud for very long they turn off. I have heard that it is necessary for your ground cable to be as big as your power cable, is that true? I have a 4 gague power wire, and 8 gague ground wire, I am not sure if that is the problem, but I want to see if people think thats what it is before I fork out much on more 4 gague wire. Thanks!
