Need help with audio setup.

Israeli_Z

So I finished the install today and I have 3 problems:

1.) There is a high pitched frequency noise that can be heard when there is no sound going through the speakers. At first it sounded like it was coming from behind me but might be the amp...hope it's not the sound of the amp operating.

2.) When starting the car up there is a pop in the speakers.

3.) I took the seat off and after reconnecting it, it still blinks for "passenger seats"

any advice? Thanks
