I am setting up my first home theater system. I have the Yamaha RX-V2300 6.1 receiver and using JBL Studio 11 series speakers for surround sound. The projector will have to wait a few months. I have got two JBL S3611 to mount at the rear center and want to check on how to wire them. My electronic technician friend says I should wire them in Parallel but have seen 3 posts here on the forum wiring two rear centers in Series. Any comments appreciated.
