Here is an old school question.My 2009 Vizio has the RCA out to my aging Sony STE-DE197 receiver which powers a pair of Sony SS7000.I'm completely satisfied with my set up but I know my Vizio isn't going to last forever.What I want to ask is if for any reason I have to upgrade and have to get a receiver that is surround sound can I use the right/left outputs to power just my two speakers.Or is there any way to make it work.Really don't want a collection of five or seven speakers on my set up cause I can rattle the pictures hanging on the wall but the neighborhood wouldn't appreciate it.I hope you can understand what I'm asking. TIA
