Depends on the quality of the speakers - I doubt that any self respecting second rate crack head would steal anything sold in a big box store. No, most thieves would likely only steal something after several auditions. So long as the abode is broken into only once - there should be no problem. What you could do is simply hook up cheap cables to the speakers; then, when the psychopath breaks in and turns the system on the sound will be so terrible he won't take anything. Use a stock power cord on the amp - just to make sure.
