This installation visit by JC was a follow up to a home sound system that was installed in 2006. My receiver had died and I called Gridworks to help me get my system back in top shape. I now have a new receiver, an updated remote and the Sonos system that now runs my external and internal speakers that were already installed. If you don't have Sonos yet, you need it, OK, you'll want it!
JC was professional and he cares about the details. He checked with me to see if I liked how he set up my components, there was an opening in the back of my cabinet that her put the wiring through a face plate to fill the opening, he set up my wireless headphones I had bought from Costco.
I recommend JC and Gridworks without hesitation. Just be prepared that you may add a new remote or Sonos to your order, even if you weren't planning on it, because these items makes your whole system that much better!
