Hi all, I currently have 2 pairs (4 speakers total) of Adept Audio rock80 speakers being driven by the Yamaha R-S202BL 200w 2-channel stereo receiver (https://a.co/d/cWgOKfS). I just purchased the TIC GS50 8" Outdoor Weather-Resistant Omnidirectional In-Ground Subwoofer (https://a.co/d/ey12IB7) and the TIC GS5-5" Compact Outdoor Weather-Resistant Omnidirectional In-Ground Speakers (https://a.co/d/4ohsZvT). I would like to power this sub and satellite speakers with a different receiver but also have this receiver be able to connect to the Yamaha system so that I can play the same music on all 6 speakers and the sub at once. I would like to know which Fosi audio system I should get that will do this (power the sub and satellite speakers separately but be able to connect to the Yamaha stereo receiver) in the proper way so that I can get the best sound but not ruin any of the equipment. Thanks in advance for everyone’s help!
