Hello, could you be a little more specific and also please tell me what happend when this problem occured. If noise on the output and amp is'nt going into protect mode, then it sounds like you may have a problem in the power supply section or the output section of the amp. If you have checked all connections and all your power and ground connections are fine and also your head unit is'nt causing the problem then it's definately internal. Sometimes the ground on the rca inputs can cause this. That's why you need to check your rca cable and the rca output of your head unit. Check all that and let me know. I do amp repairs for a living. I own a car audio installation and amp repair business and i'm the cheapest you will find for amp repairs anywhere, all with a warrant if interested. Hope this helps, let me know what you find so I can assist you further. Good luck
