Hooked up and ready for a sound test, but not the final state of the trunk. Power and ground wires will be routed better and a false floor will be created to cover the amp and crossovers and provide electric fan ventilation for the powerful amplifier. All of this is under the floor and inside the spare tire well. I have a donut spare which is under all of it just in case. Three plugs will be undone to remove the whole system for track days. Nice!
