I have a high pitch sound coming only out of my door speakers(not my sub)when I turn up the headunit about 3/4s of the way up with the sub on. But if I go into settings and turn the subwoofer off I can turn it all the way up and it won't do the highpitched noise(sounds crystal clear). I have ran a new set of rcas, replaced the headunit and still the same results. I am confused any help would be appreciated
