It is not wired up properly to the sub or what ever speakers you have hooked up to it, Or you don,t have it set up (Poperly) They do not go into the protect mode For nothing,Unless you are trying to wire up your sub or (Speakers) To lower ohms then what it is stable for.If that is the case your lucky that it hasn,t went up in smoke yet,End that is not covered buy any manufacturs Warrenty,
