A while back, I did a less than professional job installing new speaker components in each door of my 03' A4. Now, i'm getting some nasty rattling and vibrations that i'd like to get rid of.

My plan is to better secure each of these -

wiring - wrap with sound deadening sticky tape (similar to original factory wiring) + secure multiple points to the door.

crossover box - These have to remain in each door, i'm going to try a layer of padding between the crossover and it's mount point on the door frame, maybe a layer of velcro to prevent contact between the plastic and the metal.

Door panel (missing/broken clips) - (my main reason for writing this) - I can buy 'replacement' door clips from the auto store, but will they fit my a4? Where is the best place to go about getting a bunch of these clips? Do Audi dealerships have these on hand? I suppose they would since they break so easily.

Any other tips or suggestions are mucho appreciated.

Thanks!
