I have an SWS add-on sub hooked up to my Promedia 5.1 system. The mini-jack male connector pin that connects the SWS control module to the female control module port on the rear of the SWS sub produces loud noises through my speakers if the male connector pin moves or is physically touched in any way, however so slight. Could the female mini-jack control module port be defective? If so, can just this port be replaced? It seems to me that a tighter connection is required to eliminate the noise. What are your thoughts?
