Has anyone found a standard per-made box for a single 10 that will fit in the deep well, in the center of the rear of a third gen - next to the latch. I have a cvx kicker 10. Something like this.
Does port direction matte?

You'd have to have something fairly small. I had a pair of Kicker Solo 8's in the bottom of the well of my Firebird. The non-custom rectangular box was a tight fit. I had maybe a few inches unused at one end. Even without the amp rack, the well gets tight between the hatch pulldown and the package shelf. It's really only just big enough to stow a flat tire. If you can build a square box to fill the entire bottom of the well, you might have enough volume.

im about to try these, the first link should fit no problem, the last 2 might be tight
