OK, when I installed my pioneer DEH-P7200 head unit and my boston acoustic speakers(front) I get a static coming from the speakers. It is not present if I disconnect the stock amp but would like to still have it connected. Is there any way to fix this or do I have to live without the bose amp? also, is this related to the amp recall or the fact that the pioneer head unit is 4 ohm and the bose head unit is 2 ohm? Any advice would be appreciated.
