can anybody help shed light on my speaker interference, i have a old 2003 3.0L L322 HSE and every now and then experience a loud bang from my drivers side door speaker. at first i thought somebody had thrown a rock at my car, then i usually get strange whistling and other sounds which usually eventually subsides. i have also noticed that the rear speakers don't seem to work any longer. although it is a HSE it does have the centre tv screen and the 6 disc auto changer. Any ideas anyone ?

speaker blown??

whip the card off and have a look..

thanks i will take a look,
