The Kennwood KSC-SW11 150watts sub is sitting right below the airbag frame and on top of the airduct. It is basically "framed" and held in place by those.
Additionally I used foam in critical areas the keep it from moving. Test drives proofed the concept.
I placed it up side down, so that the air duct can cool the amplifier area (if needed) and the sound waves can easily push through the mesh below (WIP). Air flow keeps it cooler to boot.
Probably the smallest active sub available. Mission "SOUND" accomplished. The boxster can now easily compete with the sound packages in modern cars.
That is all I wanted. Barely visible, but noticable (not quite the shaker, but who wants that BS).
