I have an android 7inch double din deck, 2 alpine type R 10inch and a zues amp from hifonics. For over a year everything was working correctly, then about two months ago, after about 5 minutes of listening to any audio mode, the speakers start screeching softly to loudly and don't ever stop untill the system is turned off. Music is still coming through but the screeching is intolerable. Please help!!!!!
