Has anyone designed and built an enclosure for the underside of the rear shelf of a sedan for a 10-12" sub? I do not want to sacrifice the room for my precious golf clubs and would like the factory space back.

 

This maybe what you are looking for

Thanks! I've seen that, do not want free air. Wanting a hertz or similar sub. May have to get recommendations on a good one that is similar sounding.

 

You can run a shallow mount sub but it would still need around 4- 5" of depth including the enclosure itself.

I would use birch or some other type of light wood.

 

You can't use a light wood for the enclosure. The thing will flex and resonate very badly. Either internally braced 3/4" MDF or better yet 13 ply Baltic birch. Subs put out a lot of energy. So unless that enclosure is flex free, you'll lose some of that energy.
