After installing a 4 Channel amp I'm getting a humming through all speakers.
It happens when I press the brake pedal or have my signal on and is much louder when I'm doing both at the same time. I also get a pop when turning on the rear defroster.
It gets louder the higher I set my gains.
I installed a noise filter which did absolutely nothing.
I am wondering what steps can be taken to try and narrow down what is causing this problem.
Any advice would be greatly appreciated
