Kris,
If you requested 14 ga and got 16 ga, I would have them fix it, regardless of what is involved...they made the mistake...you should not suffer for it...the plate offer is just a smoke screen.
Now, on the other hand, I have 16 ga run to my QS8's and it "sounds" to be okay...now I do not have them located as well as I thought I did but they still sound impressive. I wanted them to put 12 ga in the walls but they were going to charge me over $100 a run to put it in...
And they would not "allow"
me to run the 12 gauge myself...
It's your house...make
them fix it.
