I have a 99 Jeep Grand Cherokee with the infinity sound system!!! When the radio or the CD player is being used only a slight amount of sound comes out of the Left speakers with a lot of static.. I know little about sound systems but I think that this sounds like and issue with the Amp.. Am I correct in assuming this!!! We love the sound that we do get and would like to keep the current system!!! Any advis would be greatly appreciated!!!! The sound that comes out of the right side is perfect. Balance does nothing to change it..
