On songs with deep bass my passenger door vibrates, ive stripped off the door card but still cannot find the culprit, anyone experienced this? I dont think its the door card itself Black Range Rover Sport Supercharged 2005 with exterior overfinch bodykit

Lots of things in a door that can vibrate and wear causing movement. If the membrane is complete, it may be wear, if the door has been opened, check security of everything including loom, it could also be the speaker itself blown due to water ingress or too much boom boom.  2x TDV6. SE and HSE. Both returned to sender with issues👀
TDV8 Sport HSE...... Gone. Loved it but it didn't love me!!
Now rolling in MY10 Fullfat TDV8 Vogue. Slammed it to go round corners🙈
Cruising daily #56 mph in a Volvo V8. 😱
Lots of other toys in the cupboard...😜

With the door card installed pick a song to get the vibrations, then firmly push systematically over the whole door card to see if applying pressure in a specific location reduces/ stops the vibration. If it does you will know the approximate area from where the rattle/ vibration is coming from.

If this doesn't work remove the door card as Simple1 said and check all connections/ fixings etc. contained within the door.

I had a rattle and squeak from the rear and it was found to be worn or broken fixings of the lower boot trim/ card. I got the garage to replace all fixings and add sticky backed automotive felt tape where the trim meets the metal boot lid. Solved the problem no squeaks or rattles.
