Pioneer AVH 4000NEX Hiss
I just bought and installed a Pioneer AVH 4000NEX using pac audio adapters for the harness and steering wheel control.
I have noticed a constant white noise hiss once it is powered. Also the stereo is very loud, around 3 is loud enough to listen to everything.
I have have the pioneer 6.1 audio setup.
Is this something that can be fixed with bypassing the stock amp?
