Awesome install, I'm trying to do something simalar but to be used with a car computer instead of the dual amps. My first quick and dirty attempt at a box for the computer and amp turned out poorly and I was wondering if you could give me a couple of specs on the box you put in the spare tire well. The specs I'm most interested in are the total height of the box and what material you used (from the picture it appears the you used MDF correct?). Thank you for a response.
