Ive decided to add a sub to my pro-logic set up, but im totally confused about how it will connect to the system and work with it. I have a sigle phono socket output on my amp labled sub woofer out, can i connect it to this, becuase all the subs i have seen have 2 phono inputs. Ive also heard about speaker level wiring, will this work, and if so will it work better? My other worry is that my amp has no buttons to tell it that a sub is connnected, so will it send the same amount of bass to my front speakers as it would without a sub connected? or will it send most of the bass to the sub (like i want it to). Ive alredy looked at the home cinema set up questions on this site and it doesnt help me! So id be very gratefull if someone could explain it all, Thankx, Jon.
