Not very likely.
When they brought the Hi Fi system back in the the US after discontinuing
it for the 2010 model year they deleted tweeters from the rear of the the car in both the Hi Fi and Top Hi Fi l7 system so the number of speakers was 8 and 11 instead of the previous 10 and 13 . You may have gotten one of those somehow. I am not sure of this maybe someone else could chime in .
