Hi guys, just picked up a new av receiver and 5.1 speaker kit today and have finished wiring it up. Despite everything sounding fine i have a horrible feeling i've got some of the speakers wired up wrong, yet it all sounds fine from what I can hear. Are there any telltale signs of incorrectly wired speakers and what could happen if they're wired wrong? Like I said i'm unsure if anything is amiss because it all sounds fine, Pink Floyd sounds awesome comeing through on the Pulse DVD. There are some markings on the cable but they're very hard to see. Thanks guys.
