Hi any help would be much appreciated. Right hand side in boot of my b6 I have a standard amp and sub. Think its bose symphony setup. The sub is making a tinny noise and back speakers dont seem to be quite right. Not sure if these are related but when I unplug amp this kills back speakers. I am unsure if I should replace just sub or amp or both? And I am unsure if back speakers are faulty or damp etc. I did have a leak on my back window wiper scoosher pipe and this caused water to run down into amp and sub area! Thanks in advance.
