I read in an old archive that some company made a sub box that fit in the knockout between the seat on the E-34's. Since removal of the knockout would take a whole 10-minutes (open trunk; remove fasteners that hold carpet to back of seats; pull the 1.5" rubber pad down, remove the rubber knockout (it's perforated), then the metal knockout is visable. It's just like the K/O on an electrical box. One wap and it's out),it would seem a trunk-mount sub of any kind would be easy, especially if you use one of those sub boxes/tubes that come with an amp built-in. Just take your signal by splicing into the signal BEFORE the factory amp. RThe hole could be covered with grillcloth, then replace the leather from the armrest. This is now a port, so leave the armrest down.
I installed a set of JBL components (5 1/4" mid with 1" tweeter; $180 set) in the stock locations on the rear deck, and WOW, what a difference high, mid and low. But I still want to add a sub. In front, with a bit of surgery, I installed 3 1/2" or 4" (one or the other) in the stock location on the dashtop. The little air vents included in the cut-out can be moved out of the way without loss of use. Much improved.
The front kicks and tweeters are also on the list. The kicks are 5 1/4 but there is room for much more. Which will supply more bass.
