Lately I've been noticing the factory sub keeps turning on and off. I've heard of issues with the factory bose systems not working properly, is this a common problem? Is this a problem with the head unit or the sub or could this be a bad connection? I've also had problems with the whole system not working whenever its cold out. The headunit will be lit but there is no sound ususally until the car warms up for a bit. I'm clueless on all of this, any feedback would be great. I have a 2004 Touring with the Bose 6 CD changer with tape deck.
