At the lake house there previous owners left a Bose surround system that the TV and Blue Ray player plays through. There is an older cheaper Sony receiver that powers the Bose speakers on the patio and the dock. I do not think that there is enough power to play them correctly. The Bose system works OK using the TV and Blue Ray but think that the built in changer is shot. My plans are to keep the Bose system for the living area and just us it for TY and Blue Ray. The speakers outside have a switch downstairs to direct the sound to the dock or patio using light switches. My plan is using my old Kenwood KR-8050 (about 125 Watts RMS per channel) and I have a set of Allison II speakers that might go into the workshop. Somewhere I have an 8 disk changer that I can plug into the receive along with 2 phono inputs. I need to hook-up everything to make sure they still work. If they do, I need to get from the previous owner the wiring diagram for where the speaker wire is run and build a stand for all the equipment.
