Amp powers up but no sound?

[llamabox]

I am using the same brand head unit, amp and sub. Amp and sub I just bought today. I have hooked everything up correctly. (I do have a couple years in AC/DC circuits) I have double checked all my connections. I have power to the sub, it only powers on when the key is turned so I know the remote is right. I have chosen sub in the audio menu of the head unit, where I can pick rear/sub. The bass and treble is set to 0 on the head unit and the sub level is set at 5. No sound from the sub.

I assumed there might be an issue with the RCA wires or output so I hooked up the high end input with my rear channel wires. Then when I turn the key and turn on the head unit there is no power light on the amp.

I disconnect the sub and try the speaker on one of the rear channels without the amp. It beats just fine, so I know it's not bad.

So with RCA's it lights up but no sound.

With high level/speaker input no power light on the amp at all.

I disconnected the ground and used a set of jumper cables to ground it directly to the frame under the vehicle to see if it was just grounding off the RCA jacks. Still nothing.

Where are your settings on the amp? and FYI, a few years in AC/DC circuits means nothing. We hear that ALL of the time and I'm inclined to make a blanket statement and say that those with that background are the slowest to pick up audio knowledge.

When I started to read this I instantly thought its something with your rca cables. I would look more into that direction.
