I decided to replace the factory stereo... I had empty cargo area, so here's what I came up with.
An extremely easy to build box for roughly $100 (or less). While still being able to have plenty of leg room for rear passengers. I actually used the car area floor mat as a template, and traced it onto a sheet of cardboard. I still have a few more items to add to the box, which I'm going to hold off on saying what they are until it's all done.
I included my sketch drawing incase any of you are interested in building this same box for yourself. It's a simple easy project that you could do over the weekend.
Look below this pic for other the legroom view, and box sketch.
