NSM still exists.. you could just give them a call....

"The home owner sent me pictures of the Juke Box and it appears that there are speaker level outputs on the back of it, however when reading the manual it states that the speakers that are to be connected to these terminals can't be any less than 3 Ohms which is an issue since I am using 8 Ohm speakers."

Just to state the obvious.... 8 ohms is more than 3 ohms..... so why would that be an issue?
