Winding noise with high rpms
So my car in the last month or two has started to make an odd noise, it’s a high pitched winding or whining noise and I can’t seem to figure it out. To give some insight, I have a high powered stereo in my car, two amps. I bought a high voltage Alternator to help with it from Hawks. Well, anytime the AC is on with the amps, I hear this noise. Whenever I turn the AC off and the Amps are still on, no noise. I remove the inline fuse for both amps and turn the AC on, no noise. I asked my father about it and he says it’s the alternator making the noise because I have a bad ground somewhere. I’m starting to believe it is and just want to confirm before I go through looking at all my grounds. Mainly because if it’s the grounds for my amps, it’s gonna take a lot of work to find them since I didn’t install the stereo system.
