I searched for about an hour through the different sub box threads and found nothing in particular about a specific box style. I'm about to finally put a couple of 10's in and am wondering if anyone's used Subthump's box or any of the down firing brands? I did come across a couple of posts with boxes made into the seat and although I do like that idea, I'm not fond of shallow mount subs. So back to the box in the rear... does anyone have any experience with either or both? Thanks.
