The EDSQ 10 is pretty much the only thing that is shallow enough and seems to be the best bag for the buck. If you decide you want to sell that JL let me know as I'm looking for another one to do dual in my truck. I have the 10w3v2D4. If that's what yours in I would be interested in it maybe. I highly doubt the ED 10 is as loud as the JL. Especially since you need a very shallow sub and a very small box which means less air space. The under seat down firing boxes are much louder.
