wiring sub and amp in b5.5

[wiggley_73]

hi guys i have just fitted in my headunit in today and might require a facia plate for my single din head unit, any idea's where i could get one from? its to replace my 6cd changer from the dash below the radio unit. checked vw but they said they only do one for golf mk4 is that the same fitting?

was thinking of putting in my sub and fitting it myself, has any 1 done this in the passat b5.5?! wanted to know if i could do it myself or if i should get it done. looks pretty hard to wire through the car

thanks, kev
