Ok, I'm reading that set-up is everything and a good install is the key to good sound. Well I'm sure this is absolutely true, but what exactly is a "good" set-up? I mean as long as you plug all the wires in right and properly install your speakers correctly wouldn't that be a good install? What I'm trying to get at is to see if there is more to a good install than just putting the speakers and wires in. Better yet what is a bad install? Please shed some light on this topic.
