I bought a pair of Infinity P363's during the Fry's sale and can't seem to get them working. Working in the sense that my receivers continue to shut off. Initially I connected to a HK 1710, then the receive kept going into "deep sleep" mode. When I connected the speakers to the 1710 and played music with Bluetooth, the receiving kept shutting down. I sent the receiver back for warranty replacement. Wasn't sure if the receiver was broke to begin with as I bought it as a open item from bestbuy. Today, I thought I would try connecting speakers to my old Sony str-k520 receiver and same thing happen. Receiver kept going into protection mode with increase volume. I didn't realize the Infinity p363's were 4 ohms. What is everyone else using to run the p363's? I have a couple days to return them, but shipping is almost half of what I paid for the speakers.
