First if all, DAMN! That is going to be one brutal setup. Will you be using 1200/1 amps or something more conventional? I have never had anything remotely close to this power class, but from an aesthetic POV, I say facing forward or up and ported. Those subs are the nicest looking subs IMO. Too unique to hide in a box. I assume the truck is a crew-cab and you are not contemplating a rat hole?
