I followed one of the stickied threads to do my amp/sub install, but now that I am finished I have no sound coming from the sub. I used a line out converter to take the signal from the old bose sub and then used rcas to connect that to my amp. The amp and sub itself are working fine because I have plugged my phone directly into the amp and played music through it. All the setting on the headunit seem fine as well.

Any help would be greatly appreciated. This is 2003 g35 sedan by the way.
