Driver Side Speaker Housing Rattle
 

I enjoy the stock Scion system when EQ is dialed in, however, the driver side speaker housing rattles when playing songs with a lot of bass. Even dialing bass setting down to 0, still does it. Housing is cheap plastic. What is the easiest/cheapest fix for this? Dynomat?

Does the total door panel have to be removed or does just the speaker section pop off?

I had the same issue in my BRZ but oddly enough it seemed to fix it self after about a day. Not sure how the equalizer is set up on the RFS but I also lowered the lows a tad which seemed to help as well.

Take it to the dealer. It's a new car. Speaker rattle are unacceptable on brand new unless you already blew the speaker.
