Hi all, new here and just have a quick question to ask..

i have an onkyo ht-s680...which i bought on a clearance sale and love it...but i recently moved in with a friend who has already wired his "theater" room for his old kenwood 5.1 system.

i want to show him what a much better system can sound like but since he only wired for 2 rear speakers, and doesn't really want to run more wires just for this temporary arrangement, i was wondering if i can safely run mine without the rear center hooked up?

also how will it effect the sound? i don't think much actually comes through the rear center...but i may not have it adjusted right either...still new at adjusting them properly...

thanks all
