i built it with a slot port. look awsome cant wait to hear it. we then welded up the amp rack. its sort of like a rear strut bar. its mounted to the rear seat belt mounts., 1" squar stock across, with a steel plate welded off of it at 45 deg. then 3/16 polycarb painted gunmetal from the back and rivited to that. then we floted the amp off the colycarb a little with leds under it. my phone was dead, but I will try and get pics up soon. next is to make the trim panel, mount the battery, run wire, install front components and rear coax, then tune and enjoy.
