Does anyone experince a Rattle on the rear deck with the sub on in an A4 sedan? any ideas on what to do to fix it besides dynamat?

Thanks

I have the same problem. I was thinking about building a replacement shelf, with ports, out of a beefier material. Perhaps just porting the stock shelf will yield the same results. Let me know what you come up with.

porting should reduce the rattle but might not solve it
