Hi, I have an AV Yamava v385 that i use as 2.1 (2 Dynavoice Challanger s-6 ex4 speakers and 1 sub Dynavoice Challanger sub-12) and i want to know what is thel better way to connect the subwoofer, with LFE , R-L rca or high line? I use the system for music (hip-hop and electronic) and occasionally for movies.
