Hi - I should start with I dont know much about the music side of things in cars!!
Basically I got a Audi A3 1.8 T (2002) (with Bose) (With Chorus Stereo System)
And the subwoofer seems to have blown - either that or it's a loose connection and cuts out on ever y drum beat due to chance (I think we can say it must be broke)
I have no clue where to start!!
