[QUOTE="Rurockn, post: 425703, member: 553103"] I have had a Pioneer GMX544 for about three/four years now and have never had any problems with it. About a week ago I thought that my front components were dieing on me because they would sound nasty at times, then perfect at other times. They didn't clip, just sounded horrible. This week I started the car one day and had the horrible whiney sound coming from the front speakers, the rears still sound perfect. I tried bench testing it and found out that the rca input that is linked to the rca output on the amp has the whine problem. The rca input that is not linked to the output on the amp has no problems. What I find odd is that that the problem happens on and off, and occurs more and more. At first it whined for only a few seconds, then quite, now it whines for several minutes then quites for a few seconds... its getting worse. Is there some sort of filter in the amplifer that is on its way out? I am very curious because I have had a friend, and heard or several other people that had this same problem with this model amplifer on the same channel. I'd like to fix it because I just ordered one of the new model Alpine's and don't have enough money for a new 4-channel. Thanks for reading!
