Does a 1999 BMW 528i E39 have a ski boot or no , I need some vent in the trunk to let the bass in the car ?

Question

If u guys have any ideas let me know .

Answer 1

Why not simply upgrade the speakers within the vehicle?

Did you know that it's only idiots that use deafening levels of bass whilst driving?..... Or idiots without real jobs that drive such vehicles?

Grow up!...Get a Phaeton...you won't need to modify it!  

Answer 2

You can answer this yourself by looking at the rear seat of your car

and verifying if there is an opening in the middle portion of the backrest

(which is usually hidden by the armrest, or some sort of movable

gate). Same thing can be achieved by looking inside the trunk towards the middle of the rear seat.

Those cars that have the through loading feature have a two piece rear seat backrest. Standard cars have a one piece backrest.
