So I have a quick question. If someone has a power amp say on the front sound stage. Your powering your left, right, and center With said power amp. Since that power amp is powering those speakers on the receiver the left, right, and center spots are open with no speakers wire going into them. Is it possible to plug in another left right and center to those open spots and basically have two sets of LCR and let the receiver power the second pair? Would this work, could it damage my receiver or would it even work and if so are there any reasons one wouldn’t want to do this? 🙏

So you are saying someone takes the pre out from an AVR to a separate power amp to run their main LCRs then hooks speakers up to the LCR outputs on the AVR?  Yes it could be done but why? Run those other speakers in a different room?

I think when you are using the LCR preouts to connect to an outboard amp, it disables the AVR's LCR speaker terminals.

I thought it would be cool to have two sets of lcr.

Just use rca Ys at the preout.

parallel or series... you have to be careful.

 

edit, I see you are using preouts with an external amp and want to add another set of speakers and let the receiver power them... I would think it would work since the signal is 'pre'.

Yes this will work also but another power amp will be needed.

You  can/will get all kind of phase, reponse anomalies.

Unless your receiver removes the signal from the internal power amp, it will work and cause no harm.  You may not like the sound.  I'd use spare amps for Atmos or some other surround channels.
