I just bought my system and I am trying to hook up the Kenwood 600 watt amp and i am trying to hook up the power and everything to get it to work and the light on the amp is not turning on and there is no power going to the subs and I have no idea what is wrong. We checked the power wires and there are no problems. The only problem that we can think of is that we are not grounding it the right way or something. Behind the head unit. On a first gen alty what is the best place to ground our wires in the trunk and what wires are the remote/RCA wires supposed to go to behind the head unit. We originally had it attached to the light blue wire coming out of the back of the head unit but then my friend said that it was the orange/black wire that was the actual ground. The head unit and all my speakers work but the amp isn't getting any power and no power is going to my subs. Thanks for reading this long message and any suggestions would be appreciated.
