I have a HT-R520 - First thing stated in the manual is 'Do Not Apply Power to the System Until All the Speakers Are Connected to the Receiver.' This practice avoids any hot connects to the speakers. As with any high-outpiut system connecting spreaker wires to the system while in operation can spike the speakers as well as the amplifier curcuits. Hook up your speakers first and give it a try. Good Luck!

you can check them with a ohm meter, hook it to the wires that you hook to the reciever and if you get a reading it is good if no reading it is bad wires

you're going to need a ohm meter (good electrical testers have them) and make sure ohm ratings from speakers match the ratings for your receivers. Sounds like to much resistance for receiver(s)
