An incredible system that comes packaged very well sounds amazing, even with as little as 500 W; it rattles inside my truck. I definitely recommend watching all the installation videos on their YouTube channel before starting—this made the install a breeze once I understood where everything went. Many questions come up about where the power wire should go, and for my lightning, I ran it from the passenger side through a small opening to the undercarriage near the battery packs. Then I came up the passenger side in the rear—it's a little scary drilling into your truck, but they provide everything you need for the installation. I ended up running the ground right next to the amp; there's a factory ground nearby. I just sanded down some of the paint in the middle, and it worked perfectly.
