I spend a lot of time tinkering with the car, often outside while listening to music. Had to switch to a bluetooth speaker instead of my car stereo as the vibrations were doing my head in.
They seem to come from the rocker panels, so I'm suspecting the subs to be porting out that way.
Did any of you sort this with dynamat or similar, and where exactly did you apply it?

The subs port into the panels to provide additional volume to the enclosures. I can't hear it vibrating when driving so I've never bothered to investigate it further. Thick vinyl mastic, not foam, might damp it. You'd have to lift the car and probably pull the under body shielding to narrow down where to apply it.

I have fixed mine that way.
