I shared my subwoofer project a few weekends ago, but today I completed the rear finish panel that hides the subwoofer. I made a template from cardboard and worked that until I got a nice shape, then I transferred that design to a piece of 1/4" MDF. I cut holes for the woofers, and then stretched, glued and stapled box carpet to the whole thing. I think the subs breathe well enough and I'm not worried about damaging them now. Next up will be some tie down hooks and a large cargo net to keep things from rolling around during a spirited corner.

 

Slick! Looks great.

 

Nice! I used the same Pioneer in my rear seat delete/sub install.
