I've searched in this forum but didn't see anyone having the rattles I have.

1. I have rattle coming from the rear, but this rattle is caused by the bass if music is playing. Is this normal? I've read people having rattle coming from the rear sunshade but I think mine is different. The rattle is definitely caused by the bass, but not sure if it's the subwoofer or the rear sunshade that's causing the rattle. Anyone has this issue and a fix probably?

2. The second rattle is from the gear box. It's like a clicking sound and happens when I accelerate or decelerate, so it's not constant. I pressed around the gear box area and I could hear the rattle exactly the same as when I accelerate/decelerate.

I'm due for my oil change this monday and wonder if I should have the dealer fix them. I don't want them to tear apart and cause more problems. I'm ok with the gearbox rattle, but the rattle caused by the bass is really disappointing. I have the lower the bass when I hear the rattle and thus could not enjoy the full clarity and power of the bass. Any thoughts is greatly appreciated. Thanks.
