I'm going to pick up a set of HC6 speakers and probably an Onkyo TX-SR302 receiver from J&R in a few days. What type of cables will I need to connect the speakers to the receiver? I know I need RCA to minijack to connect them to my soundcard, what do I need to connect them to my TV for the time being? Also, in a smaller dorm room, will the cable gauge make much of a difference?
