I have a Samsung Ht-E550W Home theater system and 4 Boston Audio SX Satellite Speakers with a BIC America F-12 Powered Sub. The only "good" way I can hook up my sub to the system using decent wire is by connecting via two female spade connectors into a 24K gold solder RCA connector. This is the only Sub Out on the system. The sub works GREAT while the home theater system is on, however when I turn it off with the sub in the "auto off" position, the sub hums violently, I can stop the humming by puling out slightly on the RCA connector, but essentially that is disconnecting the sub from the system entirely. I have made sure the speaker wire is not running near anything electrical or magnetic, and am using 16 gauge Audiophile wire. My questions are what would make it hum once the system is powering down, and why is it not shutting off when the system shuts off if it is in "auto shutoff" mode???? I have tested both the wire and the RCA plug for correct ohms and polarity is correct. I am kind of a newb with all of this so I hope someone can help me out here.
