I shall soon be replacing the "premium" speakers in the parcel shelf of my 87 535i with a new pair of 6X9's. What is the best technique for cutting out the metal beneath the shelf to accomodate the larger speaker baskets?
The best system I've found in BMWs,using 6x9's, is to cut holes beneath the rear seat,using the 6x9's for base there facing the front seats.The sound travels throughout the car,and putting a smaller mid-range speaker on the parcel shelf,perhaps maybe even leaving the originals,if they're in good enough shape.
Using 6x9's on the rear shelf leaves them open to sun damage,ruins any hearing of rear seat passengers,and looks like they belong in a Firebird,not a BMW.
