Pardon my ignorance, but I have a SVS PC-Plus 16-46 and when I play movies with lots of loud bass, I occasstionally get a loud click during the high volume scenes. Is this the sub bottoming out? Do I possibly have it hooked up wrong? It's not like I am running my stereo really loud or anything and it only happens during really loud bass, but it concerns me. Thanks for any help you can give.
