I took advantage of the Black Friday deal here and upgraded from my VP150 to this beast. Question is, can I run this speaker with my current Receiver, Yamaha RX-V659, it's pretty powerful but outdated. I also only see 6 ohm and 8 ohm setting on it. Running M22's QS8's currently. Will I need to add a new amp (3 ch amp - L/R/C)to the receiver to run the 180? Any suggestions? Or possibly a new receiver with sufficient 4 ohm capabilities?
