just got the first pair of in-ceiling speakers installed. After countless hours and frustrations it worked the first time I turned it on!
Thanks to everyone here who helped me on this. BMXTRIX and Isiberian FTW especially. tSc speakers (IC-6.5) went in without a hitch and sound great.
I had to tell you guys because my wife isnt home yet and I needed to tell someone.
One more pair and a patio pair to go....for now...
