I am hacking an IKEA symfonisk into being a cheap, Sonos connected amp, but the speakers I would like to wire it into are not passive, but active.
I am just wondering if the fact that there is an amplifier in the sonos speaker, which is sending amplified signal to the amplifier in the powered speaker, will cause issues for the speaker and potentially result in damage.
Each Sonos speaker actually has two channels (high and low frequencies) so I would also like to sum those into one signal for each speaker.
Would something like the diagram below work?
