I am trying to hook up a Sony 333ES reviever to a pair of RP5s, a Sony Progressive Scan DVD player w/5.1 hookups. Question is I only have one sub out on back of reciever, and two subs, so do I need to get a Y-adapter and hookup both subs that way? And to I remove the gold band post out from the speaker connection on back of the rp5s once this cable is hooked up to the preouts for better sound? Thanks for your help.
