What is low impedence????????
I just saw in the title that you're getting a Low Impedance indicator on the receiver...
Following what I said earlier, when you have multiple sets of speakers selected they connect in parallel, effectively presenting a lower impedance than either pair does alone. If your receiver is warning you of Low Impedance you could
A) Ignore it if it doesn't have any audible effects; or
B) Avoid the issue by not running the speakers together or
C) If you must have them running together, wire them in series with each other to present a higher load to the amp and connect each pair of series speakers to the A or B terminals. It would look like this...
spkr A spkr B
XXXX XXXX
L ++++++++XXXX++++++++XXXX
L --------------- XXXX--------------- XXXX
XXXX XXXX
XXXX XXXX
R ++++++++XXXX++++++++XXXX
R --------------- XXXX--------------- XXXX
XXXX XXXX
Hmm, it looks like my little 'graphic' of how to connect the speakers in series didn't work out and it was wrong. They would still be parallel.
For each Channel go from Minus on the Amplifier to the first speaker, then connect the Plus of that speaker to the Minus of the second speaker; then run a wrie from the Plus of the second speaker to the Plus of the amplifier.
I found a better solution online:

Low impedance is generally considered any speaker or combination of speakers at or below 4 ohms. 8 ohms is the common nominal value for speakers. Some are higher, some lower, but the specification allows for comparisons wgen operated with a given power amplifier. Some amplifiers will have problems driving excessively low loads but usually only when driven very hard.
Why do you ask? Is there a problem?
