OK guys I didn't Wana make a thread but I'm out of ideas. I don't know what's wrong I'm getting nothing from the amp to the subs this amp is less than a day old and is doing the same thing the other amp did that was only 3 months old. Mind you it worked fine and just all the sudden stopped working one day. The power ground and signal wires are all good (I think). I'm not sure about the rcas I tried plugging in an rca cord from the headphone jack on my phone and still nothing I'm out of ideas! On the bright side I have 2 like new amps I guess haha
