yeah well i plugged in the ipod directly into the amp not using the rcas and there was no alt whine witch makes me believe that there is no issues with the amp or speakers. so my only 2 things past that is the rcas or the head unit itself. so to rule out where my reas were ran my friend had a brand new set of top end rcas. so i ran those just over the seats not under the side trim ( just a 1 min test because he wanted them back) and the alt whine was still there. witch makes me believe that the rcas are ok. so now i'm at the head unit.
