PSW450 Question

Recently purchased the PSW450 I ran it dorectly into my SOny ES home theatre and it sounds pretty good. Here is the problem, when I have the sub switched to "look for the signal from the stereo (pardon my lack of terminology) I will occasionally hear a pop as if a surge of power into the sub Almost as if when it picks up a signal to process Is this normal?
