Are you sure you are getting signal to the amp. Try another signal source. try temporarily connecting the shield of the input cable to the car body ground. The signal ground may be open in the head unit due to a previusy faulty amp.Most newer head units ave tis signal ground fused inside the head unit.Older ones ma have bunt circuit trace. If it works when you groud the input to the car body this is what has happend. The previous amp had an open power ground so the curent when to use the signal ground but it will not hold the curent so it in turn opened.
