Car audio amp/sub problem

[Jersthecool]

For any audio enthusiasts out there maybe you'll be able to figure this one out. Just went out today and bought a wiring kit, sub and box combo and amp and don't understand what I'm doing wrong or what I'm missing.

The amp turns on and off but I'm not getting anything to the sub..
So this is what I've done,
-Wired power wire to battery positive and added the inline fuse then connected to amp
-Grounded the ground wire in the trunk and connected to amp
-Connected the RCA cables first to the rear output then the subwoofer outputs
-Connected the other end to the input ports on the amp
-Connected the on/off signal wire to the deck and amp
-Connected 1 speaker wire to positive on the amp, 1 wire to negative
-Took the other end of the speaker wires and connected to those spring connections on the back of the box

Did all that and no luck the amp turns on and off with the car but the sub isn't giving me anything. I've tried switching the rca cables from rear to sw on the deck, the "subwoofer" option is turned on, on the deck, tried adjusting all the knobs on the amp and I still can't get it to work any suggestions?
