Hey all, new to the forum. I'm hoping someone can help me out. I recently purchased a 2002 XC70, and I seem to be getting distortion from the front speakers. I brought it to the local Volvo dealer where they have now replaced both front bass drivers and tweeter's 3 times now. each time has not corrected te issue. As far as they tell me, they can't find the problem. Now I just fade all of the music to the rear so i can at least listen to something. My thoughts are that either the amp in the head unit is toast, or there is a corroded/broken wire somewhere. Has anyone had this problem?
