Last week there was a discussion about contacting a sub woofer with a home theater system. I needed a y type connector and after getting the wrong one at Wally-Mart (3.5mm audio plug to two RCA male plugs). I returned that and went to the Source. They still had an older one male RCA plug to two male RCA plugs connector cable. Just what the doctor ordered. Base now sounds fine without annoying pops or hum.
