’05 chevy pu prestige 997a rs problems

I'm on the white wire. And I learned the tach into the system. But, right after I went into the door panel to tap onto the dome light wire-- the battery on the truck went dead. I lost the comms with the GMDB and everything started getting weird. I was almost there! Frustration! I think I have a problem with the IPC/DIC circuit on the truck itself. I checked this fuse and I have a half amp constant draw. I did some searching and there are a lot of hits about this. I've got a current draw problem, and adding this RS just compounded the problem.

Ok, the battery prob has just gotten worse. I had to disconnect the R'S to try to get to the bottom of the electrical issue. It now seems that my JL amps are pulling 3.4 amps current when off. I've removed the fuse from the HU so I know it is not keeping the amps on. Has anyone seen JL amps stay on like this?
