the dreaded rear shelf bass rattle!

what is actually rattling? i dynamated the entire upper portion of the rear shelf, thinking that i wouldn't have any low-frequency bass vibration, but i do. has anyone found what actually creates the rattle and where it is? thanks!

Any long, flat, thin piece of metal will rattle with the right frequency and sound level. Sounds like a job for dynamat!

like my post said, it's all dynamatted, so it's something else.

Check your speaker mounts are screwed down tight

I went on a buzz hunt looking in the same area as you...turned out to be the plastic gears in the rear seat belt retract housing. Other than take the rear seat belts out I'm kinda at a loss for what to do about it, or maybe wrap them in CLD and foam might cut it down.

I have not had much rattle in the back, but at the right frequency/volume I get a fierce rattle from the rear view mirror.

13 GT base, 3.55, Sterling Grey, MGW shifter, BMR LCA's, GT500 AB, silver RTR's, 275/40/19 Michelin pilot super sports, more stereo equipment than I will admit to, more parts to come.

i got it 90% figured out and gone....it was the plastic trim ring that site on top of the speaker. i could have removed it from the get go, but i decided not to. now it's gone and there is no more rattle. i also tightened the speaker bolts down more, and that has helped a little too. thanks for the input guys.

You can also use duct seal as a dampening material. Just wad it under the speaker frames and wrap with aluminumized duct tape. You can get a brick of the stuff for ~$10 at your local hardware store
