You need to speak to your dealer. For them to deliver a pair of speakers like that and not unbox them and set them up for you is unheard of. Also, even if a home delivery was not done, its standard practice for the dealer to unbox the speakers before he gives them to the customer, just to check for damage. You didn't get these speakers from Best Buy.
This is the 2nd post like this in the last few weeks. I tell you exactly what I told the other poster. Call your dealer and tell him to get his ass back to your house and fix this immediately. After all, you did give him $30,000. If you take it upon yourself to try and fix whatever damage there is, you're crazy. They'll probably use it as an excuse to void your warranty.
