I'm his brother, the one doing the install for him. I'm not completely done with it yet, I had a friend that got in a wreck and needed a new system put in his new truck, and its taking longer than expected. Y'all will get to see pics of both installs once done. Amprack is coming, bracing the box, and we haven't figured out which way is loudest yet, subs up, subs back, or subs forward. The box is about 9ft^3 net @ ~34Hz.
