ditto - I also have the speaker upgrade and the columbus. Sounds pretty decent until you put in a DVD or anything with a lot of bass and I get the low bass rattle from the right hand door speaker. I think it sounds like a fault but not so convinced now. Wasn't that keen to go to the dealer again - my experience and views of dealers and audio is not something for a nice forum like this! I am now tempted to investigate further!

Crank your speakers up old chap and place your hand against the door panel and storage slot, rattle dissappears as you increase "pressure". As I said I find a sunglass case wedged in storage slot of door at a judicious location seems to do the trick.

Seems like a good idea; will certainly save messing around with taking door cards off etc.

Not got a spare sunglasses cases though. A tennis ball ought to work then; if I can find one.
