I've been trying to upgrade the speakers in my wife's car (1988 Jetta) and after talking to a friend, he mentioned that you can easily mount 6x9 speakers in a 4" hole by simply buying a plate that lifts the speaker 1" off the rear deck, leaving only the magnet in the 4" hole. Is this correct, and is there any downside to doing this? Her fronts are 3", so I need to add larger speakers somewhere and they will not mount in the front. Any ideas appreciated, and sorry if this is the wrong forum. ------------------ Do not taunt Happy Fun Ball.
