Yah that was me. I did a ton of metal cutting to make those drop and im in the process of making a mdf board to finish it off because I am planning on doing it in suede like the rest of my interior and trunk. I wanted to do kicker L7 8" at first but then i had 2 12" infinitys in a box that werent doing anything in my garage so i just used them instead. I think the 8"* will definately be easier to work with you will have to run like half the reccomended rms when running free air unless you somehow make a box in the trunk for them. Mine were just for show purposes but still sound pretty good for being free air. Any more questions about it, feel free to ask. Hope this helps out some.
