One of the speakers in my 2011 Volkswagen Jetta will sometimes sound like it's blown. It also cuts out completely at times and another speak did the same but only once.
At first I thought the speaker was blown, but 50% of the time it sounds perfectly normal and very clear. I'm guessing a wire is loose.
How can I open up the console of my car to check the wires? Are there any guides that show generically what each wire looks like and how to make sure they are all good and secured?
