No output from both Amps

Hello new poster, bad poster, because im posting for help and for that i am sorry. I am not pluggin another forum im just pasting my problem here http://forum.caraudio.com/vb/showthread.php?t=55438. HU Kenwood kvt-911,JLaduio 1000/1,450/4,13w7, Basically what it is I've have had this setup playing nicely for a week. I decided to adjust the sensitivity after reading several thread here. Was following along the jlaudio guidline, I was never able to get past 8,9 volts and my target was 54.7 volts for 3ohms so i gave up and put every setting back the way i had it. Well now I have no output on both my amps, there is power going to them, Green light is on. If i turn it pretty high you can sort of hear it? I dont know what to do now. I checked the rca plugs, gorund wires, settings, im just man i dont know pissed. Please help.

Were you using a test tone to set up your amp the way jl said to? If you just tryed to reach that voltage with regular music then it probobly would have been alot lower. Did you check the rca plugs behind the head-unit? It could just be a problem with your head-unit. Try hooking up another amp to the rcas and power cables going to your amp right now to see if its the amp or the head-unit or wiring.
