Did you use a wiring harness kit? A lot of times these can be a source of noise. You can use em for speaker wires and such but for constant power and ground you should run a seperate and larger guage wire.

Also, check if your x-overs are mounted anywhere near power wires, or something like power window motors and the like.

Also make sure you run the power wire and the signal wire down seperate sides of the vehicle. If you have to cross paths, do it at right angles.

it's important to check the amp grounds too, that's usually the cause of alt whine.

it seems that your fader and balance controls are an entirely different problem, probably due to a connection error with the rca's. look at where they go into the HU, and make sure they all go in the right spots. be especially careful to make sure the splitter's right, and also check it at the other end, where the rca's go into the amp.
