I ONLY have two of my klipsch RF-63's hooked up and they sound really good, but I'd rather wait a bit to see if I get a definite answer as to if it's fine to hook up the other two Klipsch's rf-63 to the same amp and run all four since I don't know much about ohm's and impedence thing with speakers and amp and what that means.
Man, Google is your friend: http://nadelectronics.com/products/h...ding-downloads
And you can then even click on their link to get the manual in PDF form. It'll tell you what you need to know.
I read another review that also talked specifically about this amp "adjusting" itself to different OHM loads...as it was designed to do.
This amp isn't even old, and there is a ton of info on it. Google, read, learn...and then come ask if confused
. Without even knowing what your Klipsch spkrs are rated (OHM-wise), I'd bet $$$ they're not below 4 ohm, which means you can safely use two per side and won't bring the load under 2ohms (which the amp is designed to handle!). Trust me on this. But better yet, try to read about it and get a personal understanding to increase your own knowledge. Enjoy your new amp!
