I have 2 12" subwoofers from my previous car that I would like to put in the Z.
I don't want to lose too much space, so I'm looking for the boxes that go to the sides of the trunk (left and right) and leave the middle section open, not the ones that mount under the strut bar.

I remember seeing pictures of it on a Blue Z a long time ago, but I can't remember the name of the manufacturer.

Does anyone know where I can get them?

 

That blue Z might be Mike aka " zcar03 ", he makes and sells those side boxes. Pictures on his site " WWW.CRAZKUSTOMS.COM ".

 

that's nice, but that's not it.

There was another setup, where the speakers are not laying so flat, they sit more vertical, i think they point almost completely sideways.
