Dash rattle mitigation - dash disassemble DIY

That's the sound I had too. The speaker is tightly mounted to the grill where it bumps out. It doesn't seem sufficient to carry the weight of the speaker and when off road, it's truly terrible.

It holds the speaker like mounting something to the bottom of a trampoline.

That’s a great description! I thought of it as being like mounting a speaker to a passive radiator. I have seen those used in a speaker cabinet with a woofer. I imagine that the speaker being mounted to something so flexible is almost as bad for audio quality as it is for rattles.

edit: poor word choice

Ah, so the noise is from the speaker bottoming out on what's below it as the dash flexes under the speaker's weight?

In my case it seems that large weight hanging off the bottom of the grill results in it simply bounching up and down to point the fasteners and contact points of the grill and dash all got noisy.

Yes, which is why I think the spacers I added to keep the fasteners under tension resolved my noises.

Me too...only my spacers were chucks of fabric I wedged in everywhere I could. Take up all that slop....

You can see in my pix I previously tried putting foam in the connection points as well buy it just didn't have a chance keeping the movement at bay. Often there are a combination of solutions and slightly different for everyone to get things quiet. I did mine as an experiment mostly. Had I known it would have a significant impact, I might have mounted the speaker with a bit more thought but I'll see how the solution lasts. It's definitely anchored more securely to solid dash components than the floppy dash grill.

Maybe the 3D printing wizards in the forum could come with a spacer/solution, with flexible filament material? @RWerksman @Sojhinn

TPU would work here, but honestly rivian should fix this. I'd talk to service.

Rivian should fix the charging pad too, yet I’m buying yours. ?

Short update. Still no rattle from that location and I think the music sound is better. I'm wondering if the speaker mounted so loosely muddied the sound and having it firmly anchored allows the driver to reproduce sound better.

Thanks for the inspiration Have Blue. I tackled this today since the squeak was killing me and it was Friday and the boss was out of town. ?. I wouldn't worry too much about the airbags. There are no sensors in there and not connected to trim that is removed in any way that I could see. I used the same method as Have Blue. I'll add some pics to help give more perspective. I used hvac foam between the hard plastic skeleton and wire mesh top by bending a few of the mesh tabs of the metal screen and laying the foam in. I also put some foam between plastic frame and speaker. 'll post a follow up if it worked or not in a week or so. Foam here.

Very nice. Thanks for adding content. I don't believe the rattle is coming from the speaker rattling against the grill. I should have clarified that. The speaker has foam around it already and was tight to the grill. I believe the weight of the speaker hanging from the grill causes the grill to bounce and rattle against it's other mounting points.

Hmm, looks like you put foam between the metal grill and plastic backing frame? You know that could very well be an issue with the two parts rattling against each other.

Yeah, that’s what I was trying to describe here:
