How do i go about putting 13 cm speakers in the doors of my mk1 ph3 1.2 ? I know that there are the brackets for the speakers in the door and that ill have to cut the door plastic bit but I dont know how to get the cables into the door.......hmmm... there is a gromet in the door and a weird block thing on the car and they kinda line up, so i was thinkin that this was the way but no idea ! HELP ME PLEASE
