We discussed hooking up my LSI25's using ycables from my subwoofer out on my Onkyo TX-SR806 to both my towers and my sub. Since I had many subwoofer cables available to me I connected two Y connectors from my sub out and ran 3 sub cables to the towers and the sub. Two questions. Every time I touch one of the cables to one tower I get a loud buzz from the sub (or tower I can't tell which as they are close to each other). Why is this? #2. Does connecting two Y connectors to the sub out on my receiver lose signal going to the towers and sub?
