I have not even touched the stereo yet. I am buying a new head unit soon but have noticed the whining noise in the speakers for sometime with the Bose system that is installed now which is original. I do not listen to the music loud either and have noticed the noise even with the volume down all the way. Could it possibly be the Bose Amp causing that which is in the trunk? Since I will be replacing the HU, is there anything special I should know about hooking it to the Bose?
