I have whining noise in my front right dash speaker and I can not seem to find out why. I moved my RCA cable on the other side of my car to get it away from the power wire, however, that did not help at all. I do not even hav an amp hooked up to the speakers so I am currently using the deck to power the speakers. I bought a ground loop isolator but then I realized I can not hook it up because theres no amp to hook it up to between the RCA's. Any ideas...Thanks
