Hi all,
So I currently some nice bookshelf speakers connected to my PC through and amp and I want to add a sub to the equation, however my amp has no sub inputs. So I was wondering if I could connect the sub to the sub connector on my PC and still have my speakers connected to the normal green audio jack at the back.

Many Thanks
