I just had my avic-f90bt installed in my 08 civic si and the place that installed it for me was basically closed before i could mess around with it. I noticed that in all of my audio sources I am getting a buzzing noise in the background as well as when there is no audio source selected. I am wondering is it possible that this could be because the installed may have hooked it up with the stock amp when he should have bypassed it. Will I get the same quality of sound i was before if he does bypass it? I want to call the store tomorrow and let them know but I am just wondering what might need to be done so I have an idea. My car has the 350 watt stereo system with 6 speakers and a stock sub...not sure if that makes a difference
thanks in advance
