JL makes a stealthbox for both variations of the front seats. The one version fits under the center console, the other is a replacement for the jumpseat cushion. Both are pretty pricey at ~$500. I'm planning to build my own custom box to fit inside the center console. I'll only be able to fit a 8" or 10" max inside it though. The only other location I've seen is inside the driver's side rear wheel well, there is a little space there to fit a 10"
