Audi system help pls

I have a 2005 E500 base without the Harmon/kardon sound system. When I am driving my speakers (sounds like mostly front drivers side) produce a horrible static noise when any bass plays. It gets worse and worse the faster I am moving but it works almost perfectly when I am parked. This has led me to believe it may be caused by the aux port vibrating or possibly just speakers going out? But i need a pro help. Video of the sound is attached

Where you mention that this happens only in drive this could be down to the installation of the RCA cables crossing power wires and providing a hiss or static noise through to the speakers. Some further information on how the installation is done may help

That sounds like a ground isolation issue so check the wiring. The faster you go, the worse it gets tells me the noise is coming from the alternator and gets worse the harder it works. What does any of this have to do with Audi though?
