May seem like an odd question, but when I bought my 2017, I did not ask for, nor pay for the premium sound package. But, when I got home with the car and looked at the "sticker" which had the features/price, etc - it indicated I had the Dolby Premium sound package. Is there I way to know by inspection if I have this? # of speakers? I can't find 8 speakers - only 7 that I can find (6 in the car + what looks like a sub-woofer in the hatch).
