Do you mean rear channels? Say both left speakers in the same input and the right speakers in a diiferent input? If so then you won't be losing and thing but power.
However if you are running all speakers in the same input you may be losing certain notes. Music is sometimes programmed to come from to different sources. Listen to some music on your headphones and take the left one off, and you may lose some of your music.
Yes, sorry. I meant one TR650 and one XR100 on the same left rear channel and one TR650 and one XR100 on the right rear channel.
I have a phoenix gold Tantrum 500.2, if i run 4 components, like 2 sets of perfects, what is the max RMS per channel i can have, or what is the max RMS each speaker can have and what configuration do the speakers have to be in parallel or series, 2ohm or 4 ohm?
