It’s obviously unique to a certain frequency.

What’s maybe even more interesting, is that I mashed the throttle pretty hard entering the freeway this weekend and I noticed the distortion coming from the center channel speaker on the aggressive throttle response sound from the engine....presumably because it is piped through the speakers! Am I crazy? I never noticed this for the first two months I owned the car, but I didn’t really mash the throttle until after the break in. I can only hear it in the center channel and only when you really get after it at the top of the rev range in the first couple gears. If I had to guess, I think its an issue with the housing being too close to the woofer, compromising extension during certain frequencies which happen to be produced with the first couple gears high reving as well as (obviously) certain songs.

OP - did you ever discuss with your dealer?
I found that after the audio system "broke in", as long as I keep the volume under 80% there are no more distortions. Other than that, its just the nature of the system I think.

Play it loud for a few hours, let it break in and see what it does.
