Hi
I have an ageing Cyrus AV8 which drives 3 Cyrus amps. The AV8 is becoming problematic and I will shortly be in the market for a new setup as Cyrus no longer support an AV solution.
I am drawn to the Wiim amps as they are a similar shoe box size, but before committing I need to know if I can do the following using three Wiim amps.
Connect my front stereo speakers - an obvious yes, and utilises, I guess the main box
Connect my rear surrounds - again an obvious yes, and using one of the other 2 boxes
The issue that I can’t find a solution to is whether I can use the third box to provide amplification to both my centre and my sub woofer. I don’t want an active sub woofer, I have a 10” bass unit fixed into a wall and the sound it produces is pretty good.
I cannot see why I can’t do what I want to do, but there is always a gnawing thought that I could spend a good chunk of cash and not be able to deliver what I need to deliver… any thoughts from you wonderful people?

Hi,
For WiiM's wireless Dolby 5.1, you must connect an active subwoofer to the Sub-out port of the leader device. Therefore, if using a passive subwoofer, you must add a separate amplifier and connect it to the Sub-out port.
 
Thanks for this, but won’t the left channel on amp 3, if connected to the subwoofer out on the main work? Or does it need a separate amp altogether?

No.
Please refer to "Section 3" of this manual.

The WiiM device (Amp 3) for the center speaker outputs audio for the center channel. It can't output audio for the subwoofer channel.
