Hi guys, I'm really really new here. I have a 5.1 speaker with RCA inputs. I need a recommendation for an amp, prefer used because i'm on a tight budget. I just want to hook up the 5.1 to my TV.

I have no freaking idea on what kind of amps are out there. I need one that supports 5.1 and HDMI. How much do these things costs and can i get a decent one (used) for rm300 to RM400??
