hey guys I have a 2004 Tahoe with Bose, no sub, xm and onstar. question is, I am going to be replacing the head unit and the door speakers. I want to get rid of the bose amp. why you ask? when it's col, below 30 degrees I have no sound, until the inside of the hoe is nice and heated up and in Iowa that is all winter, which sucks! I will eventually be adding a 5 channel amp for the componets and sub when I get the money, my question how do I loop around or bypass the bose amp? I have done lot of reading and searching and haven't found any clear answers. thanks!
