Stupid question, I imagine, but, wanting to isolate myself from other family members while listening to music, I got out an old CD player I wasn't using and I've hooked it up to an amplifier someone gave me (a cheap Harmon Kardon HVR 1510, I think it is), which seems to be designed for surround sound. Looking at the manual online, it seems to expect more than two speakers and you might have to configure it in some way? Just wondering if simply hooking up speakers to the right and left front speaker connections (ignoring the two back connections and the subwoofer connection) could in any way hurt my speakers? It's a nice pair of KEF LS50s. I've been trying to sell these, but no one's shown interest, so I thought I'd try to use them in a thrown-together second system in the bedroom. Just don't want to hurt anything. Thanks!
